how to determine the form of ser
how to add the correct spanish verb form for los alumnos
1 Answer
los alumnos is 3rd person, plural...they or ellos (person), but to conjugate the verb correctly you must also know the tense of the verb as well as the mood of the verb.
por ejemplo: (all 3rd person, plural)
los alumnos son... (present tense, indicative mood)
los alumnos eran... (imperfect past tense, indicative mood)
los alumnos sean... (present tense, subjunctive mood)
If you are just beginning your Spanish studies you are probably learning the present tense of the indicative mood for verbs. If so, son is the correct conjugation for Ser with los alumnos as the subject.
