Pronunciation

  • /ˈflɔː.ɹə/[1]

Etymology

It is borrowed from Latin Flōra (“the Roman goddess of flowers”),[2][3][4][5] from flōs (“flower”) (genitive flōris),[3][2][6][7] which is also the source of flower.[8][5] The scientific sense was taken from New Latin flora.[6][9][10] Etymonline traces the Latin noun to Proto-Indo-European *bhle- (“to blossom, flourish”), an extended form of Proto-Indo-European *bhel- (“to thrive, bloom”), and compares Middle Irish blath, Welsh blawd (“blossom, flower”) and Old English blōwan (“to flower, bloom”).[3] Barnhart relates it to bloom.[6]

Earliest recorded meaning

The Roman goddess of flowers: the OED's first record is in William Dunbar's “Goldyn Targe” (1508),[2] and Etymonline dates the sense to about 1500.[3] In poetry the name also became the personification of nature's power to bring forth flowers.[2][11]

Semantic evolution

In the 17th century the goddess's name began to be used in the titles of botanical books,[8][12][4] for example John Ray's “Flora, seu de florum cultura”;[8] Etymonline dates such titles from the 1640s,[3] and Barnhart cites Simon Paulli's “Flora Danica” of 1647.[6] Linnaeus made the usage popular in the natural sciences with his “Flora Suecica” (1745).[6][3][12] In English a flora was a descriptive catalogue of the plants of an area from 1777, in John Lightfoot's “Flora Scotica”,[2][9] and since 1778, in a letter of Gilbert White's, the word meant the plant life of a region or period itself,[2] a sense that Etymonline and Barnhart date to 1777.[3][6] Ayto notes that it came to be used like its animal counterpart fauna.[8][5] From 1874 it was also used of the plants of a type of environment,[2] and it was later extended to the bacteria and fungi of a place or of the body, as in intestinal flora.[9][10] In Cornwall, Flora day at Helston was a popular-etymology name for the 8 May festival called Furry Day,[13][2] recorded from 1790.[2]
