'irregularly-awarded' originates from the combination of 'irregularly' and 'awarded'. 'Irregularly' comes from Latin 'irregularis', where 'in-' meant 'not' and 'regularis' meant 'according to rule'. 'Awarded' comes from Old French 'eswarder', meaning 'to judge'.

'Irregularly' changed from the Latin 'irregularis' to the Middle English 'irreguler', and eventually became the modern English 'irregularly'. 'Awarded' evolved from the Old French 'eswarder' to the Middle English 'awarden', and eventually became the modern English 'awarded'.

Initially, 'irregularly' meant 'not according to rule', and 'awarded' meant 'to judge'. Over time, 'irregularly-awarded' evolved to mean 'given in a manner that is not consistent'.
