Sense: noun/1
Shortage, lack, scarcity, deficit, and dearth all describe a situation where something is not available in sufficient quantity. Shortage is the most common and neutral term, used for everything from water to staff (a water shortage, a housing shortage). Lack is broader — it can mean a complete absence (a lack of evidence), whereas shortage implies some exists but not enough. Scarcity is more formal and often suggests natural or structural limitation (the scarcity of clean water in the region). Deficit is used in technical or financial contexts (a budget deficit, a trade deficit). Dearth is a more literary word meaning a severe shortage (a dearth of good ideas). Use shortage for everyday situations; use lack when the absence is near-total; use scarcity for formal or environmental contexts.

Etymology
Shortage comes from the adjective 'short' (from Old English 'sceort', meaning not long, insufficient) combined with the suffix '-age', which forms nouns indicating a condition or amount (borrowed from Old French through Middle English). The word has been used since the 1600s to describe a lack or deficiency in quantity.
