What we need to consider when we want to conjugate verbs is: , , and if the subject is .

Questions to ask yourself (in that order, hint hint, wink wink):

-Are we dealing with the present, past or future?
-Is/Are the subject(s) first, second or third person?
-How many subjects are there?

Here's some more info.
First person: I (singular) / We (plural
Second person: You (singular and plural -yes, it can be both)
Third person: He/She/It (singular) / They (plural)

*** "It" is a dummy subject because it acts in place of an object or an abstract concept. English needs the dummy subject because there always has to be a subject, unline in spanish. Also, the plural of "it" is NOT "its" but "they" becuase it's the third person. ***
