complémenter

Complémenter is a rare verb meaning to complement or supplement something (complémenter un régime alimentaire) — largely overshadowed in everyday French by the far more common compléter, and sometimes criticized as an unnecessary anglicism when used loosely.

• Ce produit est censé complémenter l'alimentation quotidienne. — This product is meant to supplement the daily diet.
• Les deux approches se complémentent bien. — The two approaches complement each other well.
• On préfère généralement dire compléter plutôt que complémenter. — People generally prefer to say compléter rather than complémenter.

In most everyday contexts, native speakers reach for compléter instead of complémenter — using complémenter isn't wrong, but it can sound like an unnecessary anglicism outside specialized fields like nutrition.
