Final answer:
Reflexive verbs require the reflexive pronoun 'se' to indicate that the subject of the verb is performing the action on themselves.
Step-by-step explanation:
In Spanish, reflexive verbs are used to indicate that the subject of the verb is performing the action on themselves. Some examples of reflexive verbs are lavar (to wash oneself) and afeitarse (to shave oneself). These verbs require the reflexive pronoun se to be attached to the end of the verb.
For example, if you want to say 'I wash myself,' you would say 'Yo me lavo.'
Other verbs in the given list, such as 'trabajar' (to work), 'bañar' (to bathe), and 'vivir' (to live), are not reflexive verbs and do not require the reflexive pronoun 'se.'
