Explanation:
21.
The verb preferir is a typical e to ie stem-changing verb. This change applies to all present tense forms of the verb except the nosotros form. As such, we notice that only the 'we form' of the verb is exempt from spelling changes in the present tense conjugation of preferir and other similar verbs.
The English translations of the verbs with their pronouns are:
- I prefer.
- We prefer.
- Yo prefer.
- He/she prefers.
- They prefer.
Other verbs that are conjugated like preferir are transferir and conferir.

The verb ser means 'to be' and is used to talk about permanent characteristics. A few examples would be:
- Son las ocho de la mañana. (it is eight o'clock in the morning.)
- Soy una persona amable. (I am a friendly person.)
- ¿Por qué eres tan listo? (Why are you so smart?)
Ser is also an irregular verb as it experiences conjugation changes that do not mirror the normal changes used for verbs ending in -er. This irregularity applies not only in the present tense, but also in the imperfect and past tenses.
The meanings of the verbs and their pronouns conjugated above are the the following:
- I am.
- We are.
- You are.
- He/she/it is.
- They are.
