| 词汇 | niche |
| 词根词缀 | 词源： 1611, "shallow recess in a wall," from Fr. niche "recess (for a dog), kennel," 14c., perhaps from It. nicchia "niche, nook," from nicchio "seashell," probably from L. mitulus "mussel," but the change of -m- to -n- is not explained. Another suggestion is that the word is from an O.Fr. noun derived from nichier "to nestle, nest, build a nest," via Gallo-Romance *nidicare from L. nidus "nest;" but that has difficulties, too. Figurative sense is first recorded 1725. Biological use dates from 1927. |
