'regularly-given' originates from the combination of 'regularly' and 'given', where 'regularly' comes from Latin 'regularis' meaning 'consistent' and 'given' from Old English 'giefan' meaning 'to bestow'.

'regularly' evolved from the Latin 'regularis' through Old French 'reguler', and 'given' from Old English 'giefan', eventually forming the modern English term 'regularly-given'.

Initially, 'regularly' meant 'in a straight line' and 'given' meant 'to bestow', but over time they evolved to mean 'consistently' and 'provided', respectively.
