Learn Hardcore French: Ce sac est léger.

Use ce when you want to point to or single out a specific bag (like “this one here”).
Use le when you are talking about the bag in a more neutral, non‑pointing way, for example:

Le sac est léger. = The bag is light.
Ce sac est léger. = This/that bag is light. (more contrastive or deictic)

Why is it ce sac and not cet sac or cette sac?

French has different forms of “this/that” depending on gender and the starting sound of the noun:

ce
- masculine noun starting with a consonant: ce sac, ce livre
cet
- masculine noun starting with a vowel or mute h: cet ami, cet homme
cette
- any feminine noun: cette valise, cette chaise
ces
- any plural noun: ces sacs, ces valises

Since sac is masculine and starts with a consonant, you must say ce sac.

Why is the adjective léger placed after the noun, when in English we say “light bag”?

In French, most adjectives normally come after the noun:

un sac léger = a light bag
une voiture rouge = a red car

Some common adjectives, often very short and subjective (like beau, bon, petit, grand, vieux, nouveau, jeune, mauvais) usually come before the noun:

un petit sac
un grand sac

But léger is not one of those common “before-noun” adjectives, so the standard order is:

Ce sac est léger.
Un sac léger.

Putting léger before the noun (un léger sac) is either incorrect or would sound very literary/poetic in special contexts.

How do I make this sentence feminine or plural?

You need to change both the demonstrative and the adjective to agree with the noun.

Feminine singular (e.g. “suitcase” = valise, feminine):

Cette valise est légère. = This suitcase is light.

Changes:

ce → cette (feminine demonstrative)
léger → légère (add ‑e; pronunciation changes slightly)

Masculine plural:

Ces sacs sont légers. = These bags are light.

Changes:

ce → ces (plural)
léger → légers (add ‑s, not pronounced)

Feminine plural:

Ces valises sont légères. = These suitcases are light.

Adjective endings:

masculine: léger
feminine: légère
masculine plural: légers
feminine plural: légères

How do you pronounce Ce sac est léger?

Rough guide in English sounds:

Ce ≈ “suh”
sac ≈ “sak” (final c is a hard k sound)
est ≈ “eh”
léger ≈ “lay‑zhay”
- g before e is like zh (as in “measure”)
- final r is pronounced, but softly in the throat

So the whole sentence is roughly: “suh sak eh lay‑zhay”.

Phonetic (IPA) version: [sə sak ɛ le.ʒe].

What is the role of the accent in léger?

The accent aigu (´) over é changes both the sound and sometimes the meaning:

é is pronounced like the “ay” in “say” (closed sound)
e without accent can be various sounds or often reduced like “uh”

So léger is pronounced [le.ʒe], not like “leh‑zher”.

Also, the accent distinguishes it from other forms (for example, leger would be unusual/misspelled in standard French; léger is the correct form).

Can I also say Il est léger or C’est léger instead of Ce sac est léger?

Yes, but they don’t mean exactly the same thing.

Ce sac est léger.
- Very clear: “This/that bag is light.”
- Explicitly names the bag.
Il est léger.
- “It is light.”
- Refers back to a masculine noun that was already mentioned, e.g. le sac.
- You’d normally say this right after identifying the object:
  - Regarde ce sac. Il est léger. = Look at this bag. It is light.
C’est léger.
- “It’s light.” (more general/impersonal comment)
- Can refer to something just shown, but is more like giving an evaluation.
- Example: someone hands you a bag, you lift it and say: C’est léger !

So Ce sac est léger is the clearest if you want to explicitly talk about this/that bag.

Is there any liaison in Ce sac est léger?

Normally, you would not make a liaison in everyday speech here:

Ce sac est léger → [sə sak ɛ le.ʒe] (no extra link)

Technically, a liaison between a singular noun and a following verb (sac est → [sak‿ɛ]) is possible in very formal or careful speech, but in normal conversation most speakers do not pronounce a liaison there.

So you can safely say it with no liaison.

Does léger only mean “not heavy,” or can it mean other things?

The core meaning is “light” (not heavy), but it has related senses:

not heavy in weight:
- Ce sac est léger. = This bag is light.
light/mild (not intense):
- un vent léger = a light wind
- un sommeil léger = light sleep
not serious / moderate:
- une punition légère = a light punishment

For light in color, French usually uses clair (e.g. bleu clair = light blue).
For light in calories, you might see léger or allégé (yaourt allégé = low‑fat yogurt).

Context tells you which nuance is intended.

How would I say the negative: “This bag is not light”?

Use the standard ne … pas negation around the verb être:

Ce sac n’est pas léger. = This bag is not light.

Notes:

ne contracts to n’ before a vowel or mute h → n’est.
The rest of the sentence stays the same.
