Stem-Changing Verbs What is a stem changing verb? Remember that a verb has two parts: 1) the stem 2) the “ar”/”er”/”ir” ending. Example: Escribir – to write (cross out the ending “er” and what is left is the stem. escribir Stem = escrib ir = ending In a stem changing verb, the stem changes though the endings follow the regular “ar”/”er”/or “ir” pattern.

Stem-Changing Verbs There are 4 different types of stem changing verbs: e-ie stem changers e – i stem changers o-ue stem changers u – ue stem changers Let’s take a look at e-ie stem changers and how to conjugate them: Querer = to want. It is an e-ie stem changing verb. It also has the endings for “er” verbs.

Querer (e-ie) – to want How to conjugate: Cross of the “er” ending and you are left with the stem “quer”. Because querer is an e-ie stem changer, we have to change the “e” in the stem to “ie” before we add our endings. IMPORTANT NOTE: Stem changing verbs NEVER EVER change their stem in the NOSOTROS/VOSOTROS forms of the verb. Yo quiero = I want Tú quieres = you want él/ella/usted quiere = he/she/you want nosotros/as QUERemos = we want Vosotros/as QUERéis = you all want Ellos/ellas/ustedes quieren= They/you guys want
