Chapter 5 - STEM Changers

In Spanish, when conjugating verbs, there are some cases where the stem of the verb changes in certain forms. However, when it comes to the "nosotros" and "vosotros" forms, the stem of the verb remains the same. This means that there is no stem change in these forms. Therefore, the statement "You do NOT stem change in the 'nosotros' or 'vosotros' forms" is true.

The verb "volver" is a stem-changing verb in Spanish. Stem-changing verbs undergo a change in the stem vowel in certain conjugations. In the case of "volver," the stem change occurs from "o" to "ue" in the present tense for the pronouns "yo," "tú," "él/ella/usted," and "ellos/ellas/ustedes." Therefore, the statement that "volver" gets an "o" to "ue" stem change is true.

The correct answer is "almorzamos." In Spanish, the verb "almorzar" means "to have lunch." When conjugating this verb for the subject "nosotros" (we), the ending "-amos" is added to the stem "almorz-." Therefore, "almorzamos" is the correct conjugation for "nosotros almorzar," meaning "we have lunch."

"My friends and I" is we/nosotros = NO stem change
Translation: My friends and I eat lunch in the cafeteria.

Use "el/ella/usted" form - need stem change
Translation: The history class starts/begins at 9.

The correct answer is "vuelvo" because "volver" is a regular verb in Spanish and when conjugated in the present tense for the first person singular (yo), the ending "-o" is added to the stem "vuelv-". Therefore, "vuelvo" is the correct form for "I return" or "I come back".

The correct answer is "empiezas". This is the correct conjugation of the verb "empezar" in the second person singular form (tú). In Spanish, verbs change their endings depending on the subject pronoun and tense. In this case, "empiezas" is the correct form for the present tense when referring to the subject pronoun "tú".

The correct answer is "duerme" because "duerme" is the correct conjugation of the verb "dormir" for the third person singular form in the present tense. In this case, the subject is "ella" which means "she" in English. Therefore, "duerme" is the appropriate form of the verb to use.

The verbs "almorzar," "volver," and "dormir" all undergo an O --> UE stem change. In these verbs, the letter "o" in the stem changes to "ue" in certain forms of the verb, such as in the present tense. "Entender" and "empezar" do not have stem changes in the present tense, so they are not included in the answer.

This verb gets a E --> IE stem change.

The correct answer is "entienden." The verb "entender" means "to understand" in Spanish. In this case, the subject is "ellos," which translates to "they" in English. The conjugation of "entienden" is the third person plural form of the verb in the present tense. Therefore, "entienden" correctly matches the subject "ellos" and means "they understand."
