| 词汇 | fern |
| 词根词缀 | 词源： O.E. fearn, from P.Gmc. *farnan (cf. M.Du. varn, Ger. Farn), from PIE *porno-, a root which has yielded words for "feather, wing" (cf. Skt. parnam "feather;" Lith. papartis "fern;" Russ. paporot; Gk. pteris "fern," pteron "feather"), from base *per- (see petition). Applied to the plant perhaps from the feather-like appearance of the fronds. The plant's ability to appear as if from nothing accounts for the ancient belief that fern seeds conferred invisibility. |
