In English we have different pairs of words like I/me, he/him, she/her, we/us, you/you which we use depending on which 'side' of a verb they're on:
e.g. She admires her
I give it to him (or, I give him it)
He gives it to me (or, He gives me it)
(Notice that in the cases with 'to', the words can switch around and the 'to' vanishes, and something very similar happens in French with verbs that have à in them)
These are called subject pronouns (left) and object pronouns (right).
French has similar pairs which we use:
|Subject Pronoun||Object Pronoun|
See how they get used in real sentences:
Note that they always come before the verb.
And when followed by a vowel or mute "h", me and te become m' and t' .
Grammar note: Remember verbs always have a subject (je/tu etc.) but only some have objects. Use object pronouns to replace nouns that are the object of the verb.
Tip: If the words "object pronoun" strike horror and panic into your heart, take a look at the cartoon video in the examples which explains them. They're actually pretty easy to figure out.
