subject: the nominal element (in a clause or sometimes a verb) that refers to the most prominent participant in the action of the verb. Often (but not always) this participant is the one that does or initiates the action named by the verb. For instance in the sentence "I saw you yesterday", the subject is the first person singular (I), who does the seeing, and the object is the second person (you). However, in the passive [2] sentence "You were seen yesterday", the subject is the second person, (you) who was seen, not the unspecified person(s) who did the seeing. [Spanish: sujeto]
