noun, feminine/toɾˈmenta/plural: tormentas
storm; thunderstorm, lightning storm
Synonyms: tempestad, tronada
From Latin tormenta, plural of tormentum. The lack of a diphthong may be explained by influence from the learned borrowing tormento, or because it may have been a nautical loan from another language such as Portuguese tormenta, or possibly Old French (cf. modern French tourmente).
