Plaisier

Plaisier is a historical French verb form that was used to mean to please or to be agreeable. It is attested in Old French and early Middle French, but it did not survive into modern standard French, where the verb plaire is used instead.

Etymology and relation to related words: Plaisier belongs to the same semantic and etymological family as the noun plaisir (pleasure). Both terms derive from the Latin placere, and they share a common lineage with the modern verb plaire and the noun plaisir.

Linguistic usage: In surviving medieval and early modern texts, plaisier appears in various inflectional shapes dependent on dialect and period, and there was no single standardized conjugation. Because it is obsolete, plaisier is mainly studied by historians and philologists as an example of historical French verb formation and the close relationship between plaire and plaisir.

Modern status: Today, plaisier is primarily of interest to scholars of historical linguistics and literature. It serves as a window into how verb forms evolved in French and how the notions of pleasing and pleasure were linguistically linked in the past.
