n. past tense, grammatical form that indicates bygone times (Grammar)
adj. that expresses a past action or a past condition
I am not a teacher, but I reckon that anything "preterite" is just something which has occured in the past.
IMHO, any verb tense referring to the past, is a preterite form.
Now, each one of them has a name and a use, but all of them are preterite.
