Objetivos<\/h3>\r\nUnderstand and use o>ue, e>ie, and e>i stem-changing verbs\r\n\r\n<\/div>\r\n

Gram\u00e1tica: Verbos con cambio de ra\u00edz<\/span> (Stem-changing verbs)<\/h3>\r\nWe\u2019ve seen a number of verbs so far that change the final vowel of their stem in some of their conjugated forms, for example: \u00a1Ay! Me duelen los pies<\/em> (doler<\/em>)<\/span>, and Los ni\u00f1os tienen diez a\u00f1os<\/em> (tener<\/em>)<\/span>. These are not random irregularities-- there are three categories of stem-changing verbs, which all follow a similar pattern of changing the last vowel of their stem in the conjugated forms where that vowel is stressed.\r\n

Here\u2019s an example of an -ER verb that has the e>ie stem change:\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n
