appointed (adj.)

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., Modern French appointer), from apointer "duly, fitly," from phrase à point "to the point," from a- "to" (see ad-) + point "point," from Latin punctum "small hole made by pricking" (from nasalized form of PIE root *peuk- "to prick").

The etymological sense is "to come to a point" (about some matter), therefore "agree, settle." The meaning "put in charge, authoritatively nominate or assign" is early 15c. Related: Appointed; appointing.

"appointed or nominated by oneself," 1750, from self- + appointed.
