perpetuer
Perpetuer is the unaccented spelling of the French verb perpétuer, which means to cause something to last or to carry on over time. In English writing, the direct equivalent is perpetuate; perpetuer appears mainly when French text is cited or when discussing French language and grammar, rather than as a standard English verb.
Etymology and forms: Perpétuer derives from Latin perpetuus, meaning perpetual, and is formed as a regular French
Usage notes: Perpetuer as a standalone English verb is not standard; English writers should use perpetuate.
