C14: (in the sense: to make right, adorn) and c15 (in the modern sense: to direct words): via Old French from Vulgar Latin addrictiāre (unattested) to make straight, direct oneself towards, from Latin ad- to + dīrectusdirect
late 14c., "to make straight," from O.Fr. adresser (13c.), from V.L. *addirectiare "make straight," from L. ad "to" + *directiare, from L. directus "straight, direct" (see direct). Meaning "to direct spoken words (to someone)" is from late 15c.; noun sense of "formal speech" is from 1751. Meaning in English expanded 17c.-18c. to the notion of directing something, as a letter, "straight" to where somebody lives. "To send as a written message" is from 1630s, which led to noun senses of "superscription of a letter" (1712) and "place of residence" (1888). Related: Addressee (1810).
