French uses peu as an adverb meaning “not very,” “hardly,” or “scarcely.” When placed directly before an adjective or past participle, it expresses a low degree of the quality described. It is common in both formal and informal speech. The construction applies to most adjectives without change in form.

Meaning and use

Peu placed before an adjective reduces the intensity of that adjective. It does not invert its meaning; it simply weakens it. In many contexts it is close to “not very.” Depending on the adjective, the resulting idea can feel almost negative, but grammatically it remains an adverb of degree.

Examples:

• Peu probable
  Not very likely
• Peu profond
  Not very deep
• Peu utile
  Not very useful
• Peu fiable
  Not very reliable

With past participles used as adjectives, peu has the same weakening effect:

• Peu convaincant
  Not very convincing
• Peu connu
  Not well known
• Peu apprécié
  Not much appreciated

Register and tone

The construction is neutral and works well in precise, factual contexts. It avoids blunt negation and provides a controlled degree of understatement. French often prefers this device where English might use “barely,” “scarcely,” or “hardly.”

Examples:

• La piste est peu visible la nuit.
  The trail is barely visible at night.
• La région est peu habitée.
  The region is sparsely populated.

Peu vs pas très and similar expressions

Peu is more concise than pas très, pas vraiment, or pas beaucoup, though the meanings overlap.

• Peu probable vs pas très probable
  Both mean “not very likely,” but peu probable is more compact and slightly more formal.
• Peu clair vs pas très clair
  Both mean “not very clear,” but peu clair tends toward a neutral, matter-of-fact tone.

Common combinations

Several adjectives frequently appear with peu, forming widely understood expressions.

Examples:

• Peu commun
  Uncommon
• Peu cher
  Inexpensive
• Peu fréquent
  Infrequent
• Peu importe
  It doesn’t matter (fixed expression; here importe is verbal, not adjectival)
• Peu probable
  Unlikely
• Peu agréable
  Unpleasant
• Peu soigné
  Careless, badly done
• Peu accueillant
  Unwelcoming

Peu with adverbs and verb phrases

Although the focus is its use before adjectives, peu also modifies adverbs and verbs. This shows its general role as an adverb of degree.

Examples:

• Il parle peu clairement.
  He speaks not very clearly.
• Elle mange peu.
  She eats little.
• Ils progressent peu.
  They are making little progress.

Compared to peu de

Peu alone is an adverb. Peu de is a determiner meaning “few” or “little” and introduces a noun. They are not interchangeable.

Examples:

• Peu compétent
  Not very competent
• Peu de compétences
  Few skills

French sometimes allows both with related meanings, but the grammar differs.

Negative prefix alternatives

Certain adjectives have negative prefixes, creating meaning overlap with peu.

Examples:

• Peu logique / illogique
  Not very logical / illogical
• Peu pratique / impraticable or pas pratique
  Not very practical / impracticable

The peu form usually sounds milder and is more frequent in everyday French.
