Translation:I got married last year.
Uh.. So is "got" that direct object? Makes no sence really. What is the meaning of a transitive verb?.. Is that a verb that can be either a noun or a verb? I have often heard it said like, "I married". "I got married" "I married that person." "I got married to that person." "You married who?" "You got married to whom?"
"To marry" is not the same as "to get married".
A transitive verb is one that takes a direct object, without any preposition needed in between (e.g. "to need"; you can't say "he needed" or "I needed" without specifiying what is needed after it). An intransitive verb, then, is one that does not take a direct object (e.g. "to wonder"; you can't say "he wondered the trip").
Technically, there is a form of "marry" that is intransitive (it's identical to "to wed")... but I'd say it's far less common than the transitive forms; I think it'd generally be considered archaic. "To get married" is also a common expression; "I got married last year" would be fine.
