Forms

portento m (plural portentos)[1] The first record is spelt portemto.[2]

Etymology

It is borrowed from Latin portentum (“omen, portent; prodigy, wonder; monster”), the neuter participle of portendō (“to foretell, presage”).[2][3][1] Nascentes calls it a learned word.[4] Bluteau (1712–1728) already derived it from the Latin verb.[5]

The same Latin word is Spanish portento, Catalan portent and Italian portento.[1][6] The English words portent and portend belong to the same Latin family.[1]

Earliest recorded meaning

Houaiss dates the first record, spelt portemto, to about 1539, and the spelling portento to about 1764.[2] In Latin a portentum was an abnormal phenomenon taken as a sign of some great event.[3]

Semantic evolution

Bluteau (1712–1728) still explains the word by the Latin portenta: apparitions such as whole armies, armed horsemen and sea battles seen in the clouds, which he puts down to the reflection and refraction of light.[5] Morais (1789) defines it as something singular, rare, extraordinary and marvellous, and quotes it of a person, era hum portento de valor “he was a marvel of courage”.[7] The sense “person of extraordinary talent” is in the modern dictionaries.[2][8][9]

Timeline

  • c. 1539 – first record, as portemto.[2]

  • c. 1764 – Houaiss's first record of the spelling portento.[2]
