frond

Etymology

It is borrowed from Latin frōns (“leaf, leafy branch, foliage”), stem frond-, genitive frondis.^{[2][3][4][5][6][7]} Linnaeus gave the Latin word a specific botanical use, as distinct from folium (“leaf”).^[2][3][4][8] Its further origin is unsettled: Barnhart makes it cognate with Old Norse brum (“leaf bud”), from Proto-Indo-European *bhrem-,^[4] Klein calls that kinship only possible,^[9] and Merriam-Webster Unabridged perhaps relates the word to brim.^[10] De Vaan reports that the connection with the Germanic words for "brim" and "bud" was made hesitantly and that other scholars thought it unsure; he also discusses a comparison with Ancient Greek θρόνα (thróna, “herbs, flowers”), which might point to a shared Mediterranean substrate word.^[11]

Earliest recorded meaning

A leaf-like organ of flowerless plants: 1785, in T. Martyn's translation of Rousseau's letters on botany.^[2][3][4] Barnhart finds it cited earlier as a Latin word in an English text, in 1753, in Chambers Encyclopaedia,^[4] and Dictionary.com dates the word 1745–55.^[7]

Semantic evolution

The word entered English as a botanical term, and botanists later made its meaning more precise.^[3] The OED defines the term as the organ formed by the union of stem and foliage in certain flowerless plants, and notes that it was formerly applied, and in general language still is, to the leaves of other plants.^[2] The Shorter Oxford names the palm and the banana among these loose uses,^[6] and general dictionaries now put the fern and the palm first.^[12][10][13] From 1846, in J. D. Dana's work on zoophytes, zoologists used it for a leaf-like expansion on certain animals.^[2] Merriam-Webster Unabridged also records it for anything that looks like a frond, quoting Edith Sitwell on the fronds of his hair.^[10] A rare verb, to wave with fronds, appears in R. D. Blackmore's Cradock Nowell (1866).^[2]
