'irregularly-carried' originates from the combination of 'irregularly' and 'carried', where 'irregularly' is derived from Latin 'irregularis', meaning 'not regular', and 'carried' is the past participle of 'carry', from Old French 'carier', meaning 'to transport'.

'irregularis' transformed into the Old French 'irregulier', and eventually became the modern English 'irregular'. 'Carier' transformed into the Middle English 'carien', and eventually became the modern English 'carry'.

Initially, 'irregularly' meant 'not regular', and 'carried' meant 'transported'. The combined term 'irregularly-carried' retains the meaning of being transported in an inconsistent manner.
