Forms

ouriço m (plural ouriços)[1] Morais's dictionary of 1813 also has the form ourizo.[2]

Etymology

It is inherited from Latin ēricius (“hedgehog”).[2][3][1][4] Cunha passes through an older form erício.[3] The initial ⟨ou-⟩ is not the regular outcome: Wiktionary allows a form Vulgar Latin *auricius, and Corominas explains it, in a wide area of the Peninsula, by the influence of auricula and auris (“ear”), used as names of shells and molluscs.[1][5]

The same Latin word is Galician ourizo, Asturian oriciu, Spanish erizo, Catalan eriçó, Occitan eriç, French hérisson, Italian riccio and Romanian arici.[1][6] The forms with ⟨o-⟩ or ⟨ou-⟩ recur in Galician, Asturian, the Spanish of Santander and French oursin (“sea urchin”).[5]

The Latin noun is derived from ēr (“hedgehog”).[7][8] De Vaan takes this from Proto-Indo-European *ǵʰḗr (“hedgehog”), a root noun to a root meaning “to bristle”, and compares Ancient Greek χήρ (khḗr), known only from Hesychius.[7]

Earliest recorded meaning

Houaiss dates the word to the 15th century, from Cunha's medieval slips, and Cunha's addenda move his first date from the 16th century to the 15th.[2][3] Cunha's article heads the sense “husk of the chestnut”, and gives ouriçado “bristling” from the 16th century.[3]

Semantic evolution

Nascentes explains the husk of the chestnut as a comparison with the hedgehog, for its spines.[4] Bluteau defines ouriço as the prickly green covering of the chestnut and adds ouriço do mar, the sea urchin; describing the walnut tree, he calls its green husk ouriço too.[9][10] Morais (1789) adds the ouriço cacheiro, the hedgehog, and a beam set with iron spikes placed at the entrance of a barrier in fortifications.[11] Later dictionaries record a siege engine of the same name, and figuratively a haughty or touchy person.[12][13] Brazilian Portuguese uses the word for a spiked metal holder for flower arrangements, and in slang for great excitement or a lively party.[2][14]
