v.

late 14c., “to decide, resolve; to arrange the time of (a meeting, etc.),” from anglo-french appointer, old french apointier “make ready, arrange, settle, place” (12c.), from apointer “duly, fitly,” from phrase à point “to the point,” from a- “to” (see ad-) + point “point,” from latin punctum (see point (n.)). the ground sense is “to come to a point (about some matter),” therefore “agree, settle.” meaning “put (someone) in charge” is early 15c. related: appointed; appointing.
