'initially-completed' is a compound word formed from 'initially' and 'completed'. 'Initially' originates from the Latin word 'initialis', meaning 'beginning', and 'completed' comes from the Latin 'completus', meaning 'filled up'.

'Initially' evolved from the Latin 'initialis' through Old French 'initial', while 'completed' evolved from Latin 'completus' through Old French 'completer'.

Initially, 'initially' meant 'at the beginning', and 'completed' meant 'filled up'. Together, they describe something finished at the start.
