意味

A suffix attached to names of stores, inns, and Japanese-style restaurants, or to words describing a trade or occupation, indicating a place of business or the person running it.

や is one of the most productive suffixes in Japanese for forming compound nouns related to businesses and occupations. When attached to a product name, it indicates the shop that sells it: 花屋 (flower shop), パン屋 (bakery), 本屋 (bookshop). It can refer either to the establishment itself or to the person who runs it, depending on context: パン屋に行く (go to the bakery) vs. パン屋のおじさん (the bakery man). Some compounds with 屋 carry a slightly informal or old-fashioned nuance compared to more formal alternatives using 店 (てん). The suffix also appears in traditional business names (越後屋, 三河屋) and occupational terms (不動産屋 for estate agent, 引っ越し屋 for movers). When used for people, it can sometimes carry a mildly derogatory nuance (嘘つき屋, 怠け者屋).
