Past tense of 'haven'; sheltered or provided with refuge in a harbor or safe place.
From 'haven' (Old English 'hæfen,' from Old Norse 'höfn,' meaning harbor) plus the past tense suffix '-ed'. Originally 'haven' meant both the physical place and the action of sheltering there.
Haven started as a physical place but became a verb meaning 'to shelter'—by the 1500s, poets were writing about being 'havened' against storms, using a place-name as an action word. This shows how nouns and verbs blur together in poetic language.
