A habitation or dwelling; a place where someone lives (archaic or dialectal term).
From Latin 'habitare' meaning 'to live' or 'to dwell' (source of 'habitat'). The term 'hab' is largely archaic English, though it survives in scientific nomenclature and regional dialects.
While 'hab' is old-fashioned, you still see it in science when we talk about 'habitats'—it's the same root meaning 'where something lives.' NASA even uses 'hab' for 'habitat' in their Mars colony plans!
