'irregularly-transported' originates from the combination of 'irregularly' and 'transported'. 'Irregularly' comes from the Latin 'irregularis', meaning 'not regular', and 'transported' comes from the Latin 'transportare', meaning 'to carry across'.

'Irregularly' evolved from the Latin 'irregularis' through Old French 'irregulier', and 'transported' evolved from the Latin 'transportare' through Old French 'transporter'.

Initially, 'irregularly' meant 'not following a regular pattern', and 'transported' meant 'carried across'. The combined term retains these meanings in modern usage.
