berth · noun, verb1
- Middle English · inherited frombirth“(nautical) bearing away or off, clearance, berth”
- English todayberth
The noun is derived from Late Middle English birth (“(nautical) bearing away or off, clearance, berth”). Further etymology uncertain, but probably from beren (“to carry (away), bear”) + -th (suffix denoting a condition, quality, state of being, etc., forming nouns); if so, the English word is analysable as bear + -th (suffix forming nouns from verbs), and is a piecewise doublet of birth. The verb is derived from the noun.
