Learn French: Je me débarrasse du bazar, je le jette. - I am getting rid of the clutter, I am throwing it away.

This is because the two verbs work differently. The verb se débarrasser (to get rid of) is always followed by the preposition de. Since bazar is masculine, de + le becomes du. However, the verb jeter (to throw away) takes a direct object without a preposition. So, to say 'I throw it away', we just use the direct object pronoun le.

Why does jette have two 't's?

The infinitive is jeter (with one 't'), but it is a stem-changing verb. When the stress falls on that syllable, like in the je, tu, il/elle, and ils/elles forms in the present tense, the 't' doubles so that the 'e' before it makes an 'eh' sound. In forms like nous jetons, where the stress is on the ending, it keeps a single 't'.

Could I just say je débarrasse le bazar instead of je me débarrasse du bazar?

Not quite! While débarrasser exists without the reflexive pronoun me, it generally means 'to clear' (like clearing a table: débarrasser la table). To mean 'to get rid of' something, you must use the reflexive form se débarrasser de.

How would I use the restrictive negation ne... que to say 'I am only getting rid of the clutter'?
