bottomless
UK: ˈbɒtəmləs | US: ˈbɑːtəmləs
adj. having no bottom; extremely deep or limitless
adj. (figurative) inexhaustible or boundless
The word combines "bottom" (from Old English botm, meaning "foundation" or "lowest point") with the suffix "-less" (from Old English -lēas, meaning "without"). Originally literal (e.g., a bottomless pit), it later gained figurative use (e.g., bottomless energy) to emphasize boundlessness. The morphemes reflect a straightforward Germanic construction.

Legends speak of a bottomless lake hiding ancient secrets.
