Duplicer

Duplicer is a French verb meaning to create a duplicate or exact copy of something. It is used for copying data, documents, objects, or any item that benefits from a replica. The word traces to Latin duplicare, passing into Old French and then into modern French. It is a regular -er verb and follows standard conjugation patterns: je duplique, tu dupliques, il/elle duplique, nous dupliquons, vous dupliquez, ils/elles dupliquent.

In everyday and technical French, duplicer is widely used in computing, office work, and media. You can duplicer un fichier, duplicer une présentation, or duplicer une photo. In a backup or archival context, duplicating data is a common practice to ensure recoverability. The nuance of duplicer emphasizes creating an exact copy rather than a paraphrase or reformulation.

Grammatical notes include common tenses: passé composé J’ai dupliqué, imperfect Je dupliquais, future Je dupliquerai, conditional Je dupliquerais. The passive voice is formed with être, as in Le fichier a été dupliqué. Although rarely used in everyday speech, the passé simple exists in literary contexts as Je dupliquai / il dupliqua.

See also: copier, reproduire, répliquer. In science, the related noun duplication (la duplication) and the concept of gene duplication are used to describe the process of creating an extra copy of a genetic segment.
