depletion
dih-PLEE-shun
/dɪˈpliːʃn/
A serious reduction in the number or quantity of resources, species, or essential substances available.
Implies progressive emptying or draining of a reservoir until critical shortages occur.
The story behind the word. Latin 'plere' meant to fill (found in words like 'plenty' and 'complete'). Adding 'de-' inverted the action: 'deplere' meant to un-fill, undo the filling, or completely empty out a container.

- exhaustion: 'Exhaustion' implies the absolute total end of a supply, whereas 'depletion' highlights the process of severe reduction.
- drainage: 'Drainage' often refers physically to liquids flowing out, whereas 'depletion' applies to any finite biological or physical asset.
- replenishment: The act of refilling or restoring a supply.

Memory hook
DE-PLENISH: Undo the PLENTY until empty. De- (undo) + Plere (fill) = Un-fill completely.
When not to use
Do not use for temporary, easily fixable minor drops in inventory; use 'shortage' or 'reduction' instead.
