Address

As a noun, an address is the details of where someone lives or where a building is located. As a verb, to address can mean to speak to someone, to write the destination on something, or to deal with a problem.

From Old French 'adrecier', meaning 'to straighten, direct, or set right', from 'à' (to) + 'drecier' (to direct). The sense of 'speaking to' grew from the idea of directing words to someone.
