"J'ai besoin du balai que tu as utilisé ce matin."

Translation: I need the broom you used this morning.

[SallyGreen3]

I need the brush that you were using this morning should be accepted. We generally sweep the floor with brushes in the UK

[sophoeuf]

how come its du balai and not le?

[Seattle_Scott]

En français c'est "avoir besoin de quelque chose",
J'ai besoin de le balai.
De + le = du
J'a besoin du balai.

[Hwin_74]

Great question and great answer!

[GrahamWarr]

In my English, I'd usually put "that" before "you".

[Seattle_Scott]

It can be either

[JeanP15]

No - brush would be standard UK usage. Brooms are rather archaic these days. I say keep broom if you like, but brush should be accepted, too.

[penalpie]

Why not 'I need the broom that you were using this morning' ?

[Joanielovesjoe]

I need the broom that you used this morning seems more appropriate. It is more precise.
