Lesson 13: Possessive and demonstrative determiners

Part 1: The core flip for English speakers

In English, possessives are about the owner:

• his book = a book belonging to a man
• her book = a book belonging to a woman

In French, the possessive is about the noun. Livre (book) is masculine, so:

• son livre = his book and her book — same word.
• sa voiture = his car and her car — same word (voiture is feminine).

The French listener picks up "whose" from context, not from the possessive itself. The form son / sa / ses tells you the noun's gender and number — nothing about the owner's sex.

The trap stated bluntly: son does not mean "his". It means "his/her + masculine noun". Sa does not mean "her". It means "his/her + feminine noun". Strip the English instinct now or it will fight you for years.

Part 2: Possessives — one owner (my, your, his/her)

These three sets agree with the noun:

Examples:

• mon père — my father / ma mère — my mother / mes parents — my parents
• ton frère — your brother / ta sœur — your sister / tes enfants — your children
• son livre — his/her book (masc.) / sa maison — his/her house (fem.) / ses amis — his/her friends

Plural mes / tes / ses doesn't care about gender — it covers both masculine and feminine nouns in the plural. The contrast that matters is singular vs plural, not masculine vs feminine, once you're plural.

Part 3: The mon / ma euphony trap

French hates two vowel sounds bumping into each other. So this is wrong:

• ma amie (ma + a-mie) — two vowels colliding, awful sound

The fix: in front of a feminine noun starting with a vowel (or silent h), French uses the masculine possessive mon / ton / son for the sound only. The noun stays feminine.

Critical: the word is still feminine. If you add an adjective, that adjective stays feminine:

• mon ancienne amie — my former girlfriend (ancienne, not ancien)
• mon école française — my French school

So mon in front of these words is a sound fix only, not a gender change. Think of it the same way English says "an apple" instead of "a apple" — you flip "a" → "an" purely for sound, the apple doesn't change.

Part 4: Possessives — multiple owners (our, your, their)

Easier than the mon/ma set: in the singular, gender doesn't matter at all. One form for masculine and feminine.

• notre père — our father / notre mère — our mother / nos enfants — our children
• votre maison — your house / vos livres — your books
• leur fils — their son / leur fille — their daughter / leurs amis — their friends

Trap — leur vs leurs. The -s is about the noun, not the owners. Leur maison = one house belonging to them (could be a couple, could be ten people — still one house). Leurs maisons = several houses belonging to them.

Trap — leur (possessive) vs leur (pronoun). Looks identical, two different jobs:

• Je vois leur fils. — I see their son. (leur + noun = possessive)
• Je leur parle. — I'm talking to them. (leur + verb = indirect object pronoun, Lesson 16)

Part 5: The full grid

Drill the vertical pairs: mon père / notre père, ma mère / notre mère, mes parents / nos parents. That trains the "one owner ↔ many owners" reflex faster than running rows.

Part 6: Demonstrative determiners — this / that

One word for "this, that, these, those", with four written forms depending on the noun:

• ce livre — this book
• cet homme — this man (vowel start → cet, not ce)
• cet hôtel — this hotel (silent h → still counts as vowel start)
• cette femme — this woman
• cette idée — this idea
• ces enfants — these children (pronounced say-zahn-FAHN — liaison!)

Same logic as mon before a vowel: French is dodging vowel-on-vowel. Ce + homme would be suh-OM — clunky. Cet homme is set-OM — smooth.

Ear vs eye: cet (masc. before vowel) and cette (fem.) are pronounced identically — "set". The spelling is different, the sound is the same. The listener gets nothing from this distinction; only the reader does.

This versus that — the -ci / -là fix

Ce / cet / cette / ces alone is ambiguous between "this" (near) and "that" (far). When you need to distinguish, hyphenate the noun with -ci (here) or -là (there):

• ce livre-ci — this book (right here)
• ce livre-là — that book (over there)
• cette robe-ci, cette robe-là — this dress, that dress
• ces enfants-ci, ces enfants-là — these children, those children

In everyday speech, French actually leans on -là for both "this" and "that" — Regarde cette voiture-là ! often just means "Look at that/this car!" The -ci/-là split matters most when you're explicitly contrasting two things in front of you: Je préfère ce livre-ci à ce livre-là — "I prefer this book to that book."

Part 8: Drills — running the same noun through all six persons

Don't conjugate a verb — conjugate the owner. Noun stays put, determiner shifts.

Drill 1: "… father"

mon père → ton père → son père → notre père → votre père → leur père

Drill 2: "… mother"

ma mère → ta mère → sa mère → notre mère → votre mère → leur mère

Drill 3: "… parents"

mes parents → tes parents → ses parents → nos parents → vos parents → leurs parents

Drill 4: "… girlfriend / female friend" — the vowel trap!

mon amie → ton amie → son amie → notre amie → votre amie → leur amie

Drill 5: demonstratives — "this/that …"

ce livre → cette table → cet homme → cet hôtel → ces enfants → ces clés

Each drill out loud, three times, then once with eyes closed.
