Stem-changing verbs BOOT VERBS In the present tense
HOW do you find the stem? Drop the –ar, -er, or -ir ending The remaining portion of the word is called the stem: Example: Querer without the –er verb ending is Quer; therefore, Quer is the stem of the verb Querer.
WHEN does the stem change? Stems only change in the yo, tú, él/ella/usted, & ellos/ellas/ustedes forms. Stems DO NOT CHANGE in the nosotros and vosotros forms, which is why stem changers are often called boot verbs.
HOW does the stem change? 1. When dealing with stem-changing verbs in the present tense, only stem vowels can change. – The vowels that change are o, u or e (not a or i). 2. The four types of present tense stem- changers are: 1.o->uedormir, llover, etc. 2.e->iequerer, nevar, etc. 3.u->uejugar 4.e->iservir, pedir, etc.
WHERE does the stem change? 3.The vowel closest to the end of the word is the letter that changes. It is easy to identify the changing vowel in short words such as dormir (1 vowel in the stem), but it can get more complicated with longer words such as querer (2 vowels in the stem): Querer drop –er verb ending Quer vowel closest to the end of the word changes: Quer
