4. Ser / Ir fuifuimos fuistefuisteis fuefueron Ser and ir, although they mean completely different things, are identical in the preterit tense. Context and the a that usually follows ir are the only ways to determine whether ser or ir is being used. Miguel fue al banco. Miguel fue un alumno estupéndo. The a following fue indicates that it is a form of ir. CONTEXT: Chances are, Miguel was never a bank. This suggests that fue is not a form of ser in this sentence. The absence of a following fue indicates that it is a form of ser. CONTEXT: It is feasible that Miguel was a stupendous student, which would support the possibility that fue is a form of ser in this sentence.
