the word 'squall' presents a fascinating case of probable onomatopoeic origin, entering english from scandinavian nautical terminology. it is thought to derive from the old norse verb skvala, meaning "to shout, yell" or "to pour down, gush," capturing both the sound of a sudden cry and the rush of a sudden storm. this dual meaning was preserved as the term was adopted into middle english, likely by sailors describing abrupt, noisy weather phenomena at sea. over time, the word's usage solidified in modern english to distinctly describe both a sudden, violent gust of wind and a loud, distressed cry, linked by the core concept of a sudden, disruptive outburst.

this word is considered a simplex. it is likely of scandinavian origin, related to the swedish word skvala meaning "to gush, pour down." its functional role is as a complete lexical unit.
