| 词汇 | baby-sitter |
| 词源 | baby-sitter. Baby-sitter offers a good example of what is called back-formation of a word. Usually nouns derive from verbs, as diver derived from dive. In the case of baby-sitter, however, this process was reversed. Baby-sitter is an Ameri- canism first recorded in 1937, while the verb to baby-sit was born from it over 10 years later. The noun has come to mean one who takes care of children or anything else that requires attention. |
