The three-second test

A verb follows → qui. A subject follows → que.

Le livre qui est sur la table. /lə livʁ ki ɛ syʁ la tabl/a verb follows → qui /ki/
Le livre que je lis. /lə livʁ kə ʒə li/a subject follows → que /kə/

The English instinct here is wrong in a specific way, and knowing which way saves a lot of errors. English chooses between who and which according to whether the thing is a person or an object. French does not care about that at all. qui is not "who" and que is not "which" — qui is the subject form and que is the object form, for people and things alike.

The English pair that does map is who / whom — the one distinction English has almost abandoned. If you can say "whom", use que; if only "who" works, use qui.

How you join two sentences

Two sentencesOne
Je lis un livre. Le livre est intéressant. /ʒə li œ̃ livʁ/ · /lə livʁ ɛ.t‿ɛ̃.te.ʁɛ.sɑ̃/Je lis un livre qui est intéressant. /ʒə li œ̃ livʁ ki ɛ.t‿ɛ̃.te.ʁɛ.sɑ̃/
Voici le livre. Je lis le livre. /vwa.si lə livʁ/ · /ʒə li lə livʁ/Voici le livre que je lis. /vwa.si lə livʁ kə ʒə li/
C'est la ville. J'habite dans cette ville. /sɛ la vil/ · /ʒa.bit dɑ̃ sɛt vil/C'est la ville où j'habite. /sɛ la vil u ʒa.bit/

And one thing English lets you do that French does not: leave it out. "The book I'm reading", "the man I know" — English deletes the object relative entirely. French never deletes it. Le livre je lis is not a sentence; it must be Le livre que je lis. Whenever your English sentence has no relative word at all, French needs que.

The two English habits to unlearn

animacy and deletion

English relative pronouns encode two things French ignores:

English encodesFrench encodes
person or thing — who / whichnothing
subject or object — who / whom, barelyeverything — qui / que

So the useful move is to stop asking "is this a person?" and start asking "what job does it do in the following clause?"

The second habit is deletion. English drops the object relative more often than it keeps it — "the film I saw", "the man she married". Every one of those needs que in French. A quick check when writing: if your French relative clause starts with a subject and there is no relative word, one is missing.

And the third, smaller one: où covers both "where" and "when" after a noun. le jour où, le moment où, l'année où — never quand, which is only used to ask questions and to introduce time clauses.
