| 词汇 | pack-rat |
| 词根词缀 | 词源： common name for the N.Amer. bushytailed woodrat (Neotoma cinerea) is attested from 1885, from pack (v.), from the rodent's habit of dragging objects off to their holes. Used figuratively or allusively of persons who won't discard anything from c.1850, which means either the rat's name is older than that or the human sense is the original one. |
