Qu'est-ce qui + [verb] = What [does]...

Actually, in this case it really means "about Anne" and not about Anne's home. The little word "chez" can also stand for "about" and "among" in some contexts.

Chez lui c'est une obsession. -- With him it's an obsession.

Chez les Français on parle français. -- Among the French one speaks French.

Just when you thought things were simple....

Thanks Chris.

ditto for me...any responses yet?

Bonjour David,
Qu'est-ce que and que are pretty much synonymous ---> what. Qu'est-ce qui, when using this phrase, it will ALWAYS be followed by a verb whereas qu'est-ce que will be followed USUALLY by a noun or other subject in the same manner as que tu est triste instead qui est triste.
Here are a couple of links that might help:

Hopefully these additional resources can help clarify this for you.

Bonne chance et bonne continuation !

You use "Qu'est-ce qui..." if "qui" is the subject of the following sentence. And you use "qu'est-ce que..." if "que" is the direct object of the sentence. For example:

Qu'est-ce que tu as fait? -- What is it that you did? (literal translation)
Here "you" is the subject of the clause and "que" (=that) is the direct object. Hence: que.

Qu'est-ce qui fait le bruit? -- What is it that makes this noise?
"Qui" is the subject of the clause (... THAT makes the noise), hence "qui" and not "que".

Did that help any?

Bonsoir,
While I fully understand the response given by Chris, I still have a relevant question.
After re-reading this question that was posed, I have the sense that possibly we both missed the intent of the question. My take-away is this:
In what scenario would one choose to use «qu'est-ce qui» instead of just «que» and vice versa. Also in the same manner when would one use «qui est-ce qui» instead of just «qui»?
Most things concerning the French language have definite guidelines when one form is preferred over another, is there a similar guideline for these examples? I have re-read the lesson and cannot find a discernible explanation.

Merci en avance,
Ron

Hi David,

If what you are asking is the difference between: Qu'est-ce-qui? and Qu'est-ce que? both meaning 'What?', then it is a question of grammar. 'What' being the subject or the object in the sentence. Have a look at the following examples:

Qu'est-ce-qui est arrivé? ( What happened?), in this sentence 'What' is the subject of the verb to happen.

Quest-ce-que tu veux? ( What do you want?), in this sentence 'What' is the object of the verb to want.

Hope this helps!

qui sent le chocolat

Thank you Ron.

Or, alternatively, "Qui est-ce qui sent le chocolat"

Thank you.

Sorry, meant Qu’est-ce qui te manque

Bonjour Rod,
Ah, one of my favorite French verbs. Here is the lesson that covers «manquer à»:
https://kwiziq.learnfrenchwithalexa.com/my-languages/french/view/4559
Here is the lesson on using «plaire». I am sure there are other verbs in French that use the structure reversal but these are the two that I am most familiar with.
Basically, one states in French that «someone is missing to me» Quelqu'un me manque. when translated --> I miss (or lack) SOMEONE.
Please read over the two referenced lessons above and if that does not provide clarification,
here are a couple of other links that might help:

Bonne chance.
