전세방 or 전셋방 (a rented room) 전세집 or 전셋집 (a rented house) which word is correct? Even many Koreans use it incorrectly. the answer is 전세방(O) / 전셋방(X) 전세집(X) / 전셋집(O) because 방 is origin from Hanji language.
(房) but 집 is pure Korean language. it makes difference. Hanji + Hanji word = 전세 + 방 (a rented room) > 전세방 but Hanji + pure word = 전세 + 집 (a rented house) > 전셋집 It's very difficult ...
