'midpage' is a compound formed from 'mid' + 'page'. 'mid' traces back to Old English 'middel' meaning 'middle', and 'page' comes via Old French from Latin 'pagina' meaning 'a written page or sheet'.

'mid' developed from Old English 'middel' and 'page' evolved from Latin 'pagina' through Old French; the combination into the compound form 'mid-page' (later also written 'midpage') is a modern English formation describing position on a page.

Initially the elements meant 'middle' and 'page' respectively; the compound's meaning has remained literal, referring to the middle area of a page.
