Etymology
Etymology Information

'bankfull' is a Modern English compound formed from 'bank' + 'full'; 'bank' (meaning the edge of a river or mound) and 'full' (meaning filled).

Historical Evolution

'bank' comes into English via Old Norse 'bakki' (meaning 'bank, ridge') and Middle English adopted it as 'bank'; 'full' comes from Old English 'full'. These elements combined in Modern English to form the compound 'bankful'/'bankfull' used in technical contexts.

Meaning Changes

The compound originally simply described being 'as full as the bank'; over time it became a technical term in hydrology meaning the stage when water just fills the channel to the top of its banks.
