Ça and sa sound exactly the same, and native speakers mix them up too: « sa va » for « ça va » turns up in messages all the time. Telling ça vs sa in French apart is a matter of grammar. Ça is a pronoun, a short form of cela (that, it). Sa is a possessive, his or her, placed before a feminine noun.

One swap test settles it every time, and one exception, sa becoming son, catches most learners.

1. Ça vs sa: the swap test

Replace the word with cela, then with ma. Whichever still makes sense tells you how to spell it.

Word	What it is	Swap test	Example
ça	pronoun, that or it	cela fits	Ça me plaît.
sa	his or her, feminine noun	ma fits	Sa voiture est rouge.
son	his or her, masculine noun or a vowel	mon fits	Son amie arrive.
çà	here, only in çà et là	the fixed phrase	Des livres traînaient çà et là.

If cela works, write ça. If ma works, write sa.

2. Ça meaning: the short form of cela

Ça stands for cela or ce. It points to a thing, an idea or a situation, never to a person's belongings.

• Ça va ? (How are you? Literally: is it going?)
• Ça coûte combien ? (How much is it?)
• J'aime ça. (I like that.)

Ça is everyday French. In formal writing, such as a cover letter, cela reads better: cela me paraît essentiel.

3. When to write sa in French

Sa means his, her or its, and it goes before a feminine singular noun. The choice depends on the noun, not on the owner: Paul and Marie both say sa mère.

• Paul aime sa sœur. (his sister)
• Marie lave sa voiture. (her car)
• La ville et sa cathédrale. (its cathedral)

Before a plural noun, sa becomes ses: ses sœurs, ses voitures.

4. Sa vs son: the vowel exception

Before a feminine noun that starts with a vowel or a silent h, French uses son, not sa, so the two vowels do not clash. The noun stays feminine.

• son amie (not sa amie)
• son école
• son histoire

Wrong	Right	Why
Sa va bien.	Ça va bien.	cela va: a pronoun
Il a perdu ça montre.	Il a perdu sa montre.	ma montre works: possessive
Elle appelle sa amie.	Elle appelle son amie.	a vowel follows
J'aime sa.	J'aime ça.	j'aime cela
Ca dépend.	Ça dépend.	the cedilla is required

5. The c cedilla in ça

The little hook under ç turns a hard c into an s sound before a, o and u. Without it, ca would read like the start of café. The cedilla is part of the spelling, also in capitals: Ça commence.

The rules of the cedilla are on the French cedilla page. If your keyboard has no ç, the shortcuts for Mac, Windows and phones are in how to type French accents.

6. Ça and sa in the same sentence

The two often meet: Ça ressemble à sa maison (That looks like his house). Run the swap test on each word: cela ressemble works, so ça; ma maison works, so sa.

• Ça lui rappelle sa jeunesse.
• Sa fille dit que ça ira.

The short version

Cela fits: ça. Ma fits: sa. A vowel or silent h after it: son. Possessives have other sound-alike traps, such as son vs sont, and Apostrophe· trains them in dictations corrected word by word.
