A quick question about preterits
Does the preterit agree with the subject or the direct object? I think this is one of my major problems

Do you speak an Indo-Aryan Language (Hindi? Gujarati?) In those languages we conjugate the verb for the direct object in the preterit if the verb is transitive.
For instance "I read a book" in Hindi is "Maine kitaab padi" where "padi" agrees with "kitaab (book)" not "Mai" or "I (I'm a guy)".
Same in Gujarati. "Chhokraae film joi" where "joi" agrees with "film (movie)" not "Chhokraa (boy)".
In Spanish the verb is conjugated to the subject in the preterit. So "Yo lo hice" = "I did it". "hice" is conjugated to "I" since I'm the doer of the action (or more accurately, the subject).
Note that often pronouns drop (just like in Gujarati and Hindi! :D) when the information is obvious from context. For example:
"Lo hice". We know "hice" is the Yo-form of "hacer" in the preterit so We can infer ti means "Yo lo hice" or "I did it".
You're referring to preterite in verbs right? (There's some other grammatical term that sounds similar to this I think...)
Verbs that conjugate show the subject. Here is a page on the topic: http://www.studyspanish.com/lessons/pret1.htm
Anyways, if you have a sentence like: She ate the taco. (S) (V) (DO) Ella comió el taco.
You use -ió on the verb comer because it is 3rd person. I keep hesitating to say "match" because in Spanish you drop the seperate subject pronoun often, because the verb ending expresses the subject.
i.e. Comió el taco.
¡Buena suerte!
