flight (Middle English)

Where does "flight" come from?

The word 'flight' traces its roots back to the Proto-Indo-European root '*plew-' meaning 'to flow', which developed an enlargement into '*plewk-'[1][4]. This ancestry progressed through Proto-Germanic '*fleuganą' and Proto-West Germanic '*fleugan'[1][5]. Combined with the suffix '*-ðiz' and its descendants, the term formed Proto-West Germanic '*fluhti'[1][6]. This evolved into Old English as 'flyht', ultimately yielding the Middle English 'flight'[1][3].
