portal (English)

Where does "portal" come from?

The English adjective 'portal' traces its lineage back through Middle English 'portal'[1] and Old French 'portal'[2], which was formed from 'porte'[3] and the suffix '-al'. The Old French 'porte' descends from the Latin 'porta'[4], which comes from Proto-Italic '*portā'[7] and ultimately derives from the Proto-Indo-European root '*per-' meaning 'to pass through or over'[5].
