"Since you have had a hat."

[bonnie.sjoberg]

As this English is past tense, wouldn't it be more correct to say "Depuis que vous avez eu un chapeau"?

[Michi05]

They haven't introduced past tenses yet at this point, have they?
I haven't seen them in my profile until here so it was strange to see this...

[manohg01]

My thoughts exactly.....

[potato_jam]

When do you know when to use depuis que and not just depuis to mean since?

[Jobriath]

I think it is difficult to discuss the subtleties of conjunctions without a thorough grounding in tenses!

[Fairlie]

Why not "Puisque"?

[jyotilamba]

Should it not be "tu avais un chapeau?"

[A-tDR7R6F]

Wouldn't it mean: You have had a hat. Correct me if am wrong.

[tirzahbk]

What's the difference between "depuis" and "depuis que"? A little unsure about that.

[evanmcg5]

parce que should work too. it changes context, but putting a dependent clause in is strange in my opinion

[SChalliol]

The English translation makes no sense and is not even a complete sentence. It appears that "since" in this case is referring to a cause, but that should be stated with "Parce que." If it is referring to time, it should use a tense other than the present. The pluperfect (le plus-que-parfait) would make the most sense but we're not at all ready for that tense yet.
