fern

Etymology

It is inherited from Middle English fern, also ferne,^[2][3][4] inherited from Old English fearn,^[5][6][7][8] from Proto-Germanic *farnaz,^[6][3][9] which is also the source of Old Saxon farn, Middle Dutch varen, Dutch varen, Old High German farn and German Farn.^[6][3][5][9] The OED notes that it is not recorded in Old Norse.^[5] Outside Germanic, Barnhart and Klein list Middle Irish raith, Welsh rhedyn, Breton raden, Lithuanian papártis (“fern”) and Russian па́поротник (páporotnik, “fern”), and Sanskrit पर्ण (parṇá, “feather, wing, leaf”);^[3][4][10] Klein and Weekley compare Ancient Greek πτέρις (ptéris, “fern”) and πτερόν (pterón, “feather, wing”).^[4][11][8] These point to Proto-Indo-European *por-no- (“feather”),^[6][8][12] reconstructed by Kroonen as *ptorH-no-.^[9] Etymonline, following Watkins, derives this from *per- (“to lead, pass over”), as "that which carries a bird in flight",^[6] and the fern would then have been named for its feathery fronds.^[12][8][6]

Earliest recorded meaning

The plant: first recorded in the Corpus Glossary, before 800, where Old English fearn glosses Latin filix.^[13][5][14] Barnhart dates the Old English word to about 700, and the Middle English form ferne to probably before 1300.^[3]

Semantic evolution

The word has always meant the plant, used of a single plant or frond and also collectively.^[5][15] The Old English word is the first element of many place names.^[14] Attributive uses and compounds (fern-ashes, fern-bracken) appear from about 1386,^[13] and the verb fern, to cover with ferns, from about 1420.^[5] Because ferns seem to appear from nothing, people believed that fern seed made its bearer invisible, a belief recorded in English from the 1590s;^[6] Weekley explains it by the old idea that the plant grew from invisible seeds.^[11] In the dialects the word had forms such as farn in Gloucestershire, vern in Hampshire and viern in west Somerset, and many local compounds, such as fern-owl for the nightjar.^[16] In American slang it has been used for the female genitals and, on campuses, for someone who clings to the styles of the 1960s.^[17]
