I have a question on Qui est-ce? or Qu'est-ce que c'est? I have to choose which one to use. I know qui est-ce is who but can it also mean who's is it?

Question

Qui est-ce/Qu'est-ce que c'est? -Une lettre de Jon

Qui est-ce/Qu'est-ce que c'est? -Le portefeuille d'Amy

Answer 1

INTERROGATIVES:
THE SUBJECT OF A VERB:

who? whom? (persons) what? (things
qui qu'est-ce qui
qui est-ce qui
__________________________________________

DIRECT-OBJECT OF A VERAB:

qui que (qu')
qui est-ce que (qu') qu'est-ce que (qu')
__________________________________________

AFTER A PREPOSITION:

qui quoi
__________________________________________

Qui le fera? Who will do it?
Qui est-ce que le fera?

Qu'est-ce qui est tombé? What fell?

Qui cherchez-vous? Whom are you looking
for?
Qui est-ce que vous cherchez?

Que cherchez-vous? What are you looking
for?
Qu'est-ce que vous cherchez?

A qui pensez-vous? Of whom are you
thinking?

A quoi pensez-vous? Of what are you
thinking?

NOTE: 1. As an interrogative pronoun, "qui" may be used for persons in all three cases, as subject of a verb, as direct object of a verb, and after a preposition.

2. The "e" of "que" is dropped before a word beginning with a vowel; the "i" of "qui" is never dropped.

3. After the direct object forms "qui" and "que," the word order is inverted; after the long forms, the word order is regular.

D'accord? I only put the ones you asked about. Let me know when you are ready for "whose?" "which? what? " (adjective) and "which what one(s)?" (pronoun). So just let me know when you are ready for the rest of them!

Permettez moi de corriger une erreur :

On dit "Qui est-ce QUI le fera? " et non pas Qui "est-ce que le fera?"
