A clear liquid that is essential for all living things. It is used for drinking, cooking, and washing.

Uncountable noun. Do not say 'a water'. Say 'some water', 'a glass of water', 'a bottle of water'. Common collocations: tap water, mineral water, sparkling water, still water, hot water.

In English-speaking countries, tap water is generally safe to drink. Asking for 'still' or 'sparkling' (fizzy) water is common in restaurants. The phrase 'water under the bridge' means past events that should be forgotten.
