les vs. less

Many learners use les where they mean less or fewer, or leave the French article les inside English text. Below: clear rules, quick checks, and plenty of ready-to-use rewrites for work, school, and casual writing.

Quick answer

Les is a French plural definite article (the). In English, use less for uncountable amounts or degree, fewer for countable plural items, and the when you mean the (plural).

les → only correct in English when quoting or naming French terms (keep it as a title or phrase).
Use fewer for countable plurals (fewer emails, fewer students).
Use less for mass/uncountable nouns or degree (less time, less interest).
If you meant the (definite plural), use the.

Core explanation: 'les' is not an English word

Les is French for "the" (plural). If you see les inside an English sentence, it is usually a typo or an untranslated French phrase.

Decide whether the noun is countable. If you can number the items (one, two, three), use fewer. If the noun names a mass, amount, or abstract measure, use less.

Wrong (work): Les reports were sent yesterday.
Right: The reports were sent yesterday.
Correct as French title: Les Misérables (keep les in the title).

Grammar rules: fewer vs. less (short checklist)

Quick checklist: Can you count the items individually? → countable → fewer. If not → less.

Fewer = countable plural nouns: fewer errors, fewer students, fewer emails.
Less = uncountable/mass or degree: less time, less sugar, less interest.
Use the for a specific group: the cats, the students, the reports.

School - Wrong: She has les questions about the study.
School - Right: She has fewer questions about the study.
Work - Wrong: He showed les patience during the interview.
Work - Right: He showed less patience during the interview.

Hyphenation: fixed compounds with less

When less modifies a noun as a compound before that noun, hyphenate: less-than-ideal, less-than-stellar, less-than-perfect. After a verb or phrase, do not hyphenate: The result was less than ideal.

Before a noun: a less-than-perfect score.
After a verb/comparison: The score was less than perfect.
Wrong: a less than perfect result
Right: a less-than-perfect result

Spacing & typos: watch for 'les' as a slip

Common slip: dropping the second s from less → les. Also watch for glued tokens from copy/paste: les10, less10, lesstudents. Fix based on meaning and countability.

If you see 'les' in English, ask: Is this a typo for less? Or did the writer mean the or fewer?
Fix glued forms: 'less10' → 'less than 10' or 'fewer than 10' depending on countability.

Work - Wrong: We had les10 attendees.
Work - Right: We had fewer than 10 attendees.
Casual - Wrong: She wrote les time available.
Casual - Right: She wrote less time available.

Real usage and tone: formal vs. casual choices

In formal writing use fewer for countables and less for uncountables. In casual speech you'll often hear less + countable (less people); it's common but nonstandard in formal contexts.

Formal: fewer people, fewer errors, fewer applicants.
Casual speech: less people is widely heard; avoid it in reports and essays.
Fixed idioms keep less: less is more, less so, less likely.

Example (formal): Fewer than 50 applicants met the criteria.
Example (casual): There's less people here than I expected.

Test the whole sentence, not just the phrase. Context usually makes the right choice clear: countable → fewer; mass/amount → less; specific group → the.
