J) 10. What is the definition of a "stem-changing verb" in Spanish? (1 point)

a verb that is partially made of a Spanish plant
a verb that has a change in both the beginning and ending parts of the word
a verb that only changes at the ending
a verb that only exists in the Spanish language and does not translate

None of the provided options correctly defines a "stem-changing verb" in Spanish. A stem-changing verb is one in which the stem (the part of the verb before the ending) undergoes a change when it is conjugated in certain forms.

In Spanish, stem-changing verbs can be categorized based on the type of change that occurs: e-ie, o-ue, e-i, or sometimes u-ue. These changes take place in the present tense and other tenses/moods for specific conjugations, typically affecting all but the nosotros and vosotros forms in the present tense.

For example, in the verb "pensar" (to think), the stem change is e-ie:
- Yo pienso (I think)
- Tú piensas (You think)
- Él/ella/Ud. piensa (He/she/You formal think)
- Nosotros pensamos (We think) - no stem change
- Vosotros pensáis (You all think) - no stem change
- Ellos/ellas/Uds. piensan (They/You all formal think)

Therefore, a correct definition of a "stem-changing verb" in Spanish would be:

a verb that has a change in the stem (the part of the verb before the ending) in certain forms when it is conjugated.

what is is it

"Is it" is a phrase typically used in asking a question to inquire about the identity, nature, or value of an object or concept. If you meant to ask about a specific phrase or word that includes "is it," please provide more context so I can give you a precise explanation or answer. If, however, you accidentally repeated the word "is" and intended to ask "what is it," then you're likely inquiring about the definition or description of something, and I would need more details about the subject in question to give you an appropriate response.

To find the definition of a "stem-changing verb" in Spanish, you can consult a reliable Spanish grammar resource or textbook. These resources often explain the different verb conjugation patterns in Spanish, including stem-changing verbs.

In Spanish, stem-changing verbs, also known as "boot verbs," are verbs that undergo a change in the stem or root of the word when conjugated in certain forms. This change can occur in the main vowel(s) of the verb stem, typically in the present tense.

For example, the verb "poder" (to be able to) is a stem-changing verb. In the present tense, the stem changes from "poder" to "pued-" in the yo (I) and él/ella/usted (he/she/you formal) forms, but stays the same in the other forms:
- Yo puedo (I can)
- Tú puedes (you can)
- Él/Ella/Usted puede (he/she/you formal can)
- Nosotros/nosotras podemos (we can)
- Vosotros/vosotras podéis (you all can)
- Ellos/Ellas/Ustedes pueden (they/you all can)

In this case, the stem change occurs in the beginning part of the word (the main vowel), rather than at the ending. Therefore, option "b) a verb that has a change in both the beginning and ending parts of the word" would not be correct. Similarly, options "a) a verb that is partially made of a Spanish plant" and "c) a verb that only changes at the ending" are incorrect as they do not accurately describe what a stem-changing verb is in Spanish.

Therefore, the correct answer is "d) a verb that only exists in the Spanish language and does not translate" is also incorrect.
