'earlier-formed' originates from the combination of 'earlier' and 'formed', where 'earlier' is the comparative form of 'early', meaning 'before the usual or expected time', and 'formed' is the past participle of 'form', meaning 'to shape or create'.

'earlier' evolved from Old English 'ærlic', and 'formed' from Latin 'formare', meaning 'to shape'.

Initially, 'earlier' meant 'before the usual time', and 'formed' meant 'to shape'. Together, they describe something shaped at an earlier time.
