Etymology

It is inherited from Middle English fiers, borrowed from Anglo-Norman fers and Old French fiers, the nominative of fier (“wild, fierce, proud”) (modern French fier (“proud”)),[2][3][4][5][6] from Latin ferus (“wild, untamed”) (see feral),[2][3][4] cognate with Ancient Greek θήρ (thḗr, “wild animal”) and Lithuanian žvėris (“wild beast”),[2][5] from Proto-Indo-European *ghwer- (“wild beast”).[3][2] It is a rare case of a French word entering English in the nominative, because fierce was much used as an epithet and surname while its old sense, brave, was current.[3]

Earliest recorded meaning

Proud, noble, bold: in the surname Fiers, 1240, in Barnhart; the mid-13th century in Etymonline.[2][3]

Semantic evolution

Proud or haughty (about 1290) and brave or valiant (1297) are the earliest senses in the OED; they died out in the 16th century.[7][3] Ferocious and savage is used of persons from about 1300, and of animals from the late 14th century.[3][7] Of fire, wind, passion and other forces it is from before 1300,[7] and ardent or eager from 1377.[7] Of things acting strongly it is from 1912.[7] In northern Yorkshire as fierce as a blind pig meant able to do anything.[8]
