This includes most transition words, descriptive words or phrases, adjacent items, and complete ideas (complete ideas contain both a subject and a verb).\r\n<h2>Transition Words<\/h2>\r\n<div class=\"content clear-block\">\r\n\r\nTransition words add new viewpoints to your material; commas before and after transition words help to separate them from the sentence ideas they are describing. Transition words tend to appear at the beginning or in the middle of a sentence. By definition, a\u00a0transition word creates context that links to the preceding sentence. Typical transition words that require commas before and after them include <em>however<\/em>, <em>thus<\/em>, <em>therefore<\/em>, <em>also<\/em>, and <em>nevertheless<\/em>.\r\n<ul>\r\n \t<li><em>Therefore<\/em>, the natural gas industry can only be understood fully through an analysis of these recent political changes.<\/li>\r\n \t<li>The lead prosecutor\u00a0was prepared, <em>however<\/em>,\u00a0for a situation like this.<\/li>\r\n<\/ul>\r\n<div class=\"textbox shaded\">\r\n\r\n<strong>Note:<\/strong>\u00a0As was mentioned, these words require commas at the beginning or middle of a sentence.

Descriptive phrases tend to come at the very beginning of a sentence, right after the subject of a sentence, or at the very end of a sentence.\r\n<ul>\r\n \t<li><strong>Near the end of the eighteenth century<\/strong>, James Hutton introduced a point of view that radically changed scientists\u2019 thinking about geologic processes.<\/li>\r\n \t<li>James Lovelock, <strong>who first measured CFCs globally<\/strong>, said in 1973 that CFCs constituted no conceivable hazard.<\/li>\r\n \t<li>All of the major industrialized nations approved, <strong>making the possibility a reality<\/strong>.<\/li>\r\n<\/ul>\r\nIn each example, the phrase separated by the comma could be deleted from the sentence without destroying the sentence\u2019s basic meaning.\u00a0If the information is necessary to\u00a0the primary sentence meaning, it should <strong>not<\/strong> be set off by commas. Let's look at a quick example where comma usage conveys meaning:\r\n<ul>\r\n \t<li>Jefferson's son, Miles, just\u00a0started college.<\/li>\r\n \t<li>Jefferson's son Miles\u00a0just started college<\/li>\r\n<\/ul>\r\nYou would write the first sentence if Jefferson only has one son and his name is Miles. If Jefferson only has one son, then <em>Miles<\/em>\u00a0is not needed information and should be set off with commas.\r\n\r\nYou would write the second sentence if Jefferson has multiple sons, and it is his son Miles who just got into college.\u00a0In the second sentence,\u00a0<em>Miles<\/em>\u00a0is necessary information, because until his name is stated, you can't be sure which of Jefferson's sons the sentence is talking about.\r\n<div class=\"textbox shaded\">This knowledge can be very helpful when you're deciding whether or not to include commas in your writing, especially around the titles of books or articles you mention in your essay, where students tend to spray commas at the page. Often, the title is needed information.<\/div>\r\n&nbsp;\r\n<h2>Adjacent Items<\/h2>\r\nAdjacent items are words or phrases that have some sort of parallel relationship, yet are different from each other in meaning. Adjacent items are separated so that the reader can consider each item individually.\r\n<p style=\"padding-left: 30px;\">The river caught fire on July 4, 1968, in Cleveland, Ohio.<\/p>\r\nThe dates (July 4, 1968) and places (Cleveland, Ohio) are juxtaposed, and commas are needed because the juxtaposed items are clearly different from each other.

These are words that join two words or phrases of equal importance. The mnemonic FANBOYS helps us remember the seven most common: <em>f<\/em><i>or<\/i>, <i>and<\/i>, <i>nor<\/i>, <i>but<\/i>, <i>or<\/i>,\u00a0<i>yet<\/i>, and <i>so<\/i>.\r\n\r\nWhen these conjunctions join two words or phrases, no comma is necessary (for more than two, take a look at \"Commas in Lists\"\u00a0just below):\r\n<ul>\r\n \t<li>Minh turned off the lights but left the door unlocked.\r\n<ul>\r\n \t<li>\"Minh turned off the lights\" is a complete phrase; \"left the door unlocked\" is not. No comma is required before\u00a0<em>but<\/em>.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t<li>Danny studied the lifespan of rhinoceroses in\u00a0their native Kenya and the lifespan of\u00a0rhinoceroses in captivity.\r\n<ul>\r\n \t<li>\"Danny studied the lifespan of rhinoceroses in their native Kenya\" is a complete idea; \"the lifespan of rhinoceroses in captivity\" is not. No comma is required before\u00a0<em>and<\/em>.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\nWhen these conjunctions are used to join two complete\u00a0ideas, however, a comma is required:\r\n<div class=\"content clear-block\">\r\n<ul>\r\n \t<li>We could write this as two separate sentences, but we've chosen to join them together here.\r\n<ul>\r\n \t<li>Both \"We could write this as two separate sentences\" and \"We've chosen to join them together here\" are complete ideas.

There are two independent clauses, so there should be a comma before\u00a0<em>but<\/em>.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ol>\r\n[\/hidden-answer]\r\n\r\n<\/div>\r\n<h2>Commas in Lists<\/h2>\r\nThe serial comma is used to separate adjacent items\u2014different items with equal importance\u2014when there are three or more. This is so the reader can consider each item individually. Here are a few examples:\r\n<ul>\r\n \t<li>Weathering may extend only a few centimeters beyond the zone in <strong>fresh granite<\/strong>, <strong>metamorphic rocks<\/strong>, <strong>sandstone<\/strong>, <strong>shale<\/strong>, and <strong>other rocks<\/strong>.<\/li>\r\n \t<li>This approach <strong>increases homogeneity<\/strong>, <strong>reduces the heating time<\/strong>, and <strong>creates a more uniform microstructure<\/strong>.<\/li>\r\n<\/ul>\r\nIn the first sentence, the commas are important because each item presented is distinctly different from its adjacent item. In the second\u00a0example, the three phrases, all beginning with different verbs, are parallel, and the commas work with the verbs to demonstrate that \u201cThis approach\u201d has three distinctly different impacts.\r\n<h3>The Serial Comma (a.k.a the Oxford\u00a0Comma)<\/h3>\r\nPerhaps one of the most hotly contested comma conventions is the case of\u00a0the <strong>serial comma<\/strong> or the\u00a0<strong>Oxford comma<\/strong>.\u00a0MLA style (as well as\u00a0APA and\u00a0<em>Chicago<\/em>) requires the use of the serial comma\u2014AP style highly recommends leaving it out. But what is the serial comma?\r\n\r\nThe serial comma is the\u00a0comma before the<i>\u00a0<\/i>conjunction (<em>and<\/em>,\u00a0<em>or<\/em>, and\u00a0<em>nor<\/em>) in a series\u00a0involving a parallel list of three or more things.\u00a0For example, \u201cI am industrious, resourceful<strong><em>, and<\/em><\/strong> loyal.\u201d The serial comma can provide clarity in certain situations.\u00a0For example, if the <em>and<\/em> is part of a series of three or more phrases (groups of words) as opposed to single words:\r\n<p style=\"padding-left: 30px;\">Medical histories taken about each subject included smoking history, frequency of exercise, current height and weight, and recent weight gain.<\/p>\r\nThe serial comma can also prevent the end of\u00a0a series from\u00a0appearing to be a parenthetical:\r\n<p style=\"padding-left: 30px;\">I'd like to thank my sisters, Beyonc\u00e9 and Rihanna.<\/p>\r\nWithout the serial comma, it may appear that the speaker is thanking their two sisters, who are named Beyonc\u00e9 and Rihanna (which could be possible, but isn't true in this case). By adding the serial comma, it becomes clear that the speaker is thanking their sisters, as well as the two famous singers: \"I'd like to thank my sisters, Beyonc\u00e9, and Rihanna.\"\r\n\r\nBy always using a comma before the <em>and<\/em> in any series of three or more, you honor the distinctions between each of the separated items, and you avoid any potential reader confusion.\r\n<div class=\"textbox shaded\"><strong>Note:<\/strong>\u00a0Some professors and many journals prefer to leave out\u00a0the serial comma. For the journals, it is literally cheaper to print fewer commas. Because of this, the serial comma is not\u00a0recommended in AP style. When clarity, not finances, is your concern, we recommend you employ the serial comma.<\/div>\r\n<div class=\"textbox key-takeaways\">\r\n<h3>Practice<\/h3>\r\nThe commas have been removed from the following sentences. Re-type them, adding the standardized commas back in.\r\n<ol>\r\n \t<li>Ava's\u00a0favorite meals are cauliflower\u00a0soup steak and eggs lasagna and chicken parmigiana.<\/li>\r\n \t<li>Victor\u00a0tried to make\u00a0dinner for her.

We tend to make the same mistakes over and over again; in fact, many writers develop the unfortunate habit of automatically putting commas into slots such as these:\r\n<ul>\r\n \t<li>between the subject and verb of a sentence<\/li>\r\n \t<li>after any number<\/li>\r\n \t<li>before any preposition<\/li>\r\n \t<li>before or after any conjunction<\/li>\r\n<\/ul>\r\nJust as it is common for someone to have to look up the same tricky word dozens of times before committing its proper spelling or use to memory, you may need to reference comma conventions multiple times before they feel natural to use. A great place to start is by reminding yourself of the comma\u2019s basic function as a separator and justifying the separation of elements. Taking time over commas in short writing assignments or the self-checks in INTD 106 is an opportunity for breaking old habits and learning new ones before you launch into the rest of your career at Geneseo and beyond.\r\n<div class=\"textbox key-takeaways\">\r\n<h3>Practice<\/h3>\r\nRead the following sentences.

These are words that join two words or phrases of equal importance. The mnemonic FANBOYS helps us remember the seven most common: <em>f<\/em><i>or<\/i>, <i>and<\/i>, <i>nor<\/i>, <i>but<\/i>, <i>or<\/i>,\u00a0<i>yet<\/i>, and <i>so<\/i>.<\/p>\n<p>When these conjunctions join two words or phrases, no comma is necessary (for more than two, take a look at &#8220;Commas in Lists&#8221;\u00a0just below):<\/p>\n<ul>\n<li>Minh turned off the lights but left the door unlocked.\n<ul>\n<li>&#8220;Minh turned off the lights&#8221; is a complete phrase; &#8220;left the door unlocked&#8221; is not. No comma is required before\u00a0<em>but<\/em>.<\/li>\n<\/ul>\n<\/li>\n<li>Danny studied the lifespan of rhinoceroses in\u00a0their native Kenya and the lifespan of\u00a0rhinoceroses in captivity.\n<ul>\n<li>&#8220;Danny studied the lifespan of rhinoceroses in their native Kenya&#8221; is a complete idea; &#8220;the lifespan of rhinoceroses in captivity&#8221; is not. No comma is required before\u00a0<em>and<\/em>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>When these conjunctions are used to join two complete\u00a0ideas, however, a comma is required:<\/p>\n<div class=\"content clear-block\">\n<ul>\n<li>We could write this as two separate sentences, but we&#8217;ve chosen to join them together here.\n<ul>\n<li>Both &#8220;We could write this as two separate sentences&#8221; and &#8220;We&#8217;ve chosen to join them together here&#8221; are complete ideas.

There are two independent clauses, so there should be a comma before\u00a0<em>but<\/em>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n<h2>Commas in Lists<\/h2>\n<p>The serial comma is used to separate adjacent items\u2014different items with equal importance\u2014when there are three or more. This is so the reader can consider each item individually. Here are a few examples:<\/p>\n<ul>\n<li>Weathering may extend only a few centimeters beyond the zone in <strong>fresh granite<\/strong>, <strong>metamorphic rocks<\/strong>, <strong>sandstone<\/strong>, <strong>shale<\/strong>, and <strong>other rocks<\/strong>.<\/li>\n<li>This approach <strong>increases homogeneity<\/strong>, <strong>reduces the heating time<\/strong>, and <strong>creates a more uniform microstructure<\/strong>.<\/li>\n<\/ul>\n<p>In the first sentence, the commas are important because each item presented is distinctly different from its adjacent item. In the second\u00a0example, the three phrases, all beginning with different verbs, are parallel, and the commas work with the verbs to demonstrate that \u201cThis approach\u201d has three distinctly different impacts.<\/p>\n<h3>The Serial Comma (a.k.a the Oxford\u00a0Comma)<\/h3>\n<p>Perhaps one of the most hotly contested comma conventions is the case of\u00a0the <strong>serial comma<\/strong> or the\u00a0<strong>Oxford comma<\/strong>.\u00a0MLA style (as well as\u00a0APA and\u00a0<em>Chicago<\/em>) requires the use of the serial comma\u2014AP style highly recommends leaving it out. But what is the serial comma?<\/p>\n<p>The serial comma is the\u00a0comma before the<i>\u00a0<\/i>conjunction (<em>and<\/em>,\u00a0<em>or<\/em>, and\u00a0<em>nor<\/em>) in a series\u00a0involving a parallel list of three or more things.\u00a0For example, \u201cI am industrious, resourceful<strong><em>, and<\/em><\/strong> loyal.\u201d The serial comma can provide clarity in certain situations.\u00a0For example, if the <em>and<\/em> is part of a series of three or more phrases (groups of words) as opposed to single words:<\/p>\n<p style=\"padding-left: 30px;\">Medical histories taken about each subject included smoking history, frequency of exercise, current height and weight, and recent weight gain.<\/p>\n<p>The serial comma can also prevent the end of\u00a0a series from\u00a0appearing to be a parenthetical:<\/p>\n<p style=\"padding-left: 30px;\">I&#8217;d like to thank my sisters, Beyonc\u00e9 and Rihanna.<\/p>\n<p>Without the serial comma, it may appear that the speaker is thanking their two sisters, who are named Beyonc\u00e9 and Rihanna (which could be possible, but isn&#8217;t true in this case). By adding the serial comma, it becomes clear that the speaker is thanking their sisters, as well as the two famous singers: &#8220;I&#8217;d like to thank my sisters, Beyonc\u00e9, and Rihanna.&#8221;<\/p>\n<p>By always using a comma before the <em>and<\/em> in any series of three or more, you honor the distinctions between each of the separated items, and you avoid any potential reader confusion.<\/p>\n<div class=\"textbox shaded\"><strong>Note:<\/strong>\u00a0Some professors and many journals prefer to leave out\u00a0the serial comma. For the journals, it is literally cheaper to print fewer commas. Because of this, the serial comma is not\u00a0recommended in AP style. When clarity, not finances, is your concern, we recommend you employ the serial comma.<\/div>\n<div class=\"textbox key-takeaways\">\n<h3>Practice<\/h3>\n<p>The commas have been removed from the following sentences.

We tend to make the same mistakes over and over again; in fact, many writers develop the unfortunate habit of automatically putting commas into slots such as these:<\/p>\n<ul>\n<li>between the subject and verb of a sentence<\/li>\n<li>after any number<\/li>\n<li>before any preposition<\/li>\n<li>before or after any conjunction<\/li>\n<\/ul>\n<p>Just as it is common for someone to have to look up the same tricky word dozens of times before committing its proper spelling or use to memory, you may need to reference comma conventions multiple times before they feel natural to use. A great place to start is by reminding yourself of the comma\u2019s basic function as a separator and justifying the separation of elements. Taking time over commas in short writing assignments or the self-checks in INTD 106 is an opportunity for breaking old habits and learning new ones before you launch into the rest of your career at Geneseo and beyond.<\/p>\n<div class=\"textbox key-takeaways\">\n<h3>Practice<\/h3>\n<p>Read the following sentences.
