Four main constructions use the French neuter object pronoun.

1. To Replace or Refer to an Idea Contained in an Adjective, Noun, or Clause ; this is the case in the following examples:

Êtes-vous américain? Oui, je le suis. –> Are you American? Yes, I am.

Il est espion! Non, il ne l'est pas. –> He's a spy! No, he's not.

Il t'aime. J'espère que tu le comprends. –> He loves you. I hope you understand that.  

Je vais me venger. Je le jure! –> I will get revenge. I swear it!

2. In the Second Clause of a Comparison

This is the case after the words aussi, autre, autrement, comme, plus, moins, mieux. Note that the ne that shows up in the second clause of many of these examples is also optional.

Il est plus grand que je ne le croyais. –> He's taller than I thought.

Cela vaut moins que tu ne le penses. –> That's worth less than you think.

Elle est autre qu'il ne l'espérait. –> She's different than he hoped.

Il n'est pas aussi stupide qu'on le croit. –> He's not as stupid as people think.

Ce n'est pas gentil de parler des autres comme tu le fais. –> It's not nice to talk about others like you do.

3. With Negative Expressions of Opinion and Desire: 'Ne Pas Penser,' 'Ne Pas Vouloir,' 'Ne Pas Croire'

Va-t-il venir? Je ne le pense pas. –> Is he going to come? I don't think so.

Allez, viens avec nous! Je ne le veux pas. –> Come on, come with us! I don't want to.

4. With the Verbs 'Croire,' 'Devoir,' 'Dire,' 'Falloir,' 'Oser,' 'Penser,' 'Pouvoir,' 'Savoir,' 'Vouloir'

Comme vous le dites, ce n'est pas juste. –> As you say, it's not fair.
