'squall' originates from the Scandinavian language, specifically the word 'skvala,' where 'skv-' meant 'to cry out.'

'skvala' transformed into the Middle English word 'squalen,' and eventually became the modern English word 'squall.'

Initially, it meant 'to cry out loudly,' but over time it evolved into its current meanings of 'a sudden wind' and 'to scream loudly.'
