"an interpreter, a guide for travelers," c. 1300, drugeman, from Old French drugemen and directly from Medieval Latin dragumanus, from late Greek dragoumanos, from Arabic targuman "interpreter," from targama "interpret." Treated in English as a compound from man (n.), with plural -men.
late 14c., rectour (late 13c. as a surname, early 13c. in Anglo-Latin), "ruler of a country or people" (a sense now obsolete), from Latin rector "ruler, governor, director, guide," from rect-, past participle stem of regere "to rule, guide" (from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule").
The meaning "head of a college or religious community" is by early 15c., though the exact religious sense varies across place and time and with different denominations. Used originally of Roman governors and God; by 18c. generally restricted to clergymen and college heads. Fem. forms were rectress (c. 1600); rectrix (1610s). Related: Rectorship; rectorial.
