Learn French: Le banquier a tout pris dans le casino à cause de la dette. - The banker took everything in the casino because of the debt.

In compound tenses like the passé composé, the neutral pronoun tout (meaning everything) is placed between the helping verb (a) and the past participle (pris). If you said a pris tout, it would sound unnatural in French!

Does the 't' at the end of tout connect to pris?

No, the final 't' in tout is silent here. You would only pronounce it if the next word started with a vowel sound, like in il a tout oublié (he forgot everything).

Could I use parce que instead of à cause de here?

No, because parce que (because) must be followed by a full subject and verb. À cause de means 'because of' and is used before a noun, like la dette (the debt) in this sentence.

Does à cause de always have a negative meaning?

Yes, it generally implies a negative or neutral cause, like a debt. If the reason was positive, you would use grâce à (thanks to) instead.
