means A married man, considered in relation to his spouse.

from From Old English 'husbonda,' meaning the master or head of a household — a fusion of 'hus' (house) and the Old Norse 'bondi' (a freeholder or dweller, from a verb meaning to dwell or till). So the original husband was simply the man tied to the house and its land, which is why 'husbandry' still means the careful management of crops and animals. Only later did the word narrow from 'householder' to 'married man.'
