'irregularly-created' originates from the combination of 'irregularly' and 'created'. 'Irregularly' comes from the Latin 'irregularis', meaning 'not regular', and 'created' from the Latin 'creare', meaning 'to make or produce'.

'Irregularly' evolved from the Latin 'irregularis' through Old French 'irregulier', and 'created' from Latin 'creare' through Old French 'creer'.

Initially, 'irregularly' meant 'not following a rule', and 'created' meant 'to bring into existence'. Together, they describe something made without a consistent pattern.
