irrigation
ihr-uh-GAY-shuhn
/ˌɪrɪˈɡeɪʃən/
The artificial application of water to land or soil to assist in the production of crops or maintenance of lawns.
Refers to organized, engineered watering systems (like sprinklers or drip lines) rather than natural rainfall or casual hand-watering.
The story behind the word. The word flows from the Latin 'rigare', meaning to wet or moisten. In ancient Rome, 'irrigatio' referred to the complex network of aqueducts and channels built to direct water from distant rivers directly into dry agricultural fields, transforming arid landscapes into fertile farmland.

When not to use
