The Basics of Stem-Changing Verbs

Stem-changing verbs, also known as irregular verbs, are a type of verb that changes its root form when conjugated in the present tense. This means that the verb's stem changes to a new form, which can affect the entire conjugation of the verb. There are two main types of stem-changing verbs in Spanish: e/o verbs and ie/ui verbs. e/o verbs change their root vowel from "e" to "o" or vice versa, while ie/ui verbs change the "i" or "u" vowel sound to a different sound.
For example, the verb "hablar" (to speak) is an e/o verb, which changes its root vowel from "e" to "o" when conjugated in the present tense. On the other hand, the verb "vender" (to sell) is an ie/ui verb, which changes the "i" vowel sound to a different sound when conjugated.
