'whirler' originates from the English word 'whirl,' which comes from Middle English 'whirlen,' meaning 'to turn rapidly.'

'whirlen' transformed into the modern English word 'whirl,' and 'whirler' was derived from it by adding the suffix '-er.'

Initially, 'whirl' meant 'to turn rapidly,' and 'whirler' has maintained the meaning of something or someone that turns rapidly.
