  • IPA (Ecclesiastical): [ˈfiː.liks][1]

Forms

filix f (genitive filicis); third declension[1]

Etymology

It is inherited from Proto-Italic *fel-e/ik-, from Proto-Indo-European *bʰel- (“henbane”), with a suffix found in other plant names, as lārix “larch” and cārex “sedge”.[2][1] Cognate with Welsh bele (“henbane”), Russian белена (belená, “henbane”) and Old High German bilisa (“henbane”).[2] Walde and Hofmann rejected the link on semantic grounds, but Schrijver restored it: the stems of henbane look like the feathery leaves of fern, and both are medicinal plants.[2] The spelling felix may be the older form.[2][3] The OLD calls it of unknown origin.[3] Isidore of Seville derived it from its single leaf.[4]

Earliest recorded meaning

De Vaan dates it from Vitruvius, who says fern should be laid under timber.[3] Köbler's first source is Virgil, 70–19 BC.[2][3][5]

Semantic evolution

It meant a fern or bracken, often collectively, in Virgil, Horace, Columella and Pliny the Elder.[3][6] Colloquially it meant a worthless person, a no-good.[3] Persius uses it of bristly hair.[7]

In Medieval Latin filix arborea was polypody and filix silvestris the royal fern.[8] Its descendants include Italian felce, French fougère and Romanian ferigă.[1]
