A rounded protuberance or elevated mass, especially the fatty deposit on a camel's back. Can also refer to any bump or mound-like formation.
From Middle Low German humpe meaning 'hump, lump.' Related to Dutch homp and German Humpen. The word entered English in the 17th century.
Camel humps are amazing fat storage systems that can sustain the animal for weeks without food - they're basically biological fuel tanks! When depleted, the hump actually shrinks and flops to one side.
