'periodically-given' is a compound word formed from 'periodically' and 'given'. 'Periodically' originates from the Greek word 'periodikos', meaning 'recurring at intervals', and 'given' is derived from the Old English 'giefan', meaning 'to bestow or grant'.

'Periodically' evolved from the Greek 'periodikos' through Latin 'periodicus', and 'given' transformed from Old English 'giefan' to the modern English 'give'.

Initially, 'periodically' meant 'recurring at intervals', and 'given' meant 'to bestow'. Together, they convey the idea of something being provided at regular intervals.
