'growl' originates from Middle English, specifically the word 'grollen,' where 'grollen' meant 'to grumble or murmur.'

'grollen' transformed into the modern English word 'growl' through Middle English.

Initially, it meant 'to grumble or murmur,' but over time it evolved into its current meaning of 'to make a low, guttural sound, typically in anger or hostility.'
