Origin & History of “address”

Address originally meant ‘straighten’. William Caxton, e.g., here uses it for ‘stand up straight’: ‘The first day that he was washed and bathed he addressed him(self) right up in the basin’ Golden Legend 1483. This gives a clue to its ultimate source, Latin dīrectum ‘straight, direct’. The first two syllables of this seem gradually to have merged together to produce *drictum, which with the addition of the prefix ad- was used to produce the verb *addrictiāre. Of its descendants in modern romance languages, Italian addirizzare most clearly reveals its source. Old French changed it fairly radically, to adresser, and it was this form which English borrowed. The central current sense of ‘where somebody lives’ developed in the 17th and 18th centuries from the notion of directing something, such as a letter, to somebody.
