'irregularly-stopped' originates from the combination of 'irregularly' and 'stopped', where 'irregularly' is derived from Latin 'irregularis', meaning 'not regular', and 'stopped' is the past participle of 'stop', from Old English 'stoppian'.

'irregularly-stopped' combines the adjective 'irregularly' with the past participle 'stopped', forming a compound adjective used in modern English.

Initially, 'irregularly' meant 'not regular', and 'stopped' meant 'halted'. Together, they describe something that is halted in a non-regular manner.
