The Disjunctive Pronouns (aka: Stressed Pronouns, aka: Independent Pronoun).

The disjunctive or stressed pronouns look like this (you may ignore the exclamation marks!):

moi!	(I) me!
toi!	you!
lui!	(he) him, it!
elle!	(she) her, it!!
nous!	us!
vous!	you!
eux!	(they) them (masc.)
eux!	(they) them! (fem.)

Example in English:

Who is there?? It's me! (I know it should be "I," but let's talk like the rest of us do!).
Who looks like a monkey. He! or Him!
Marie-Laure and Mireille are cute. Who" They? Them?
