means A paddy is a flooded field where rice is grown, or by extension the rice crop itself (especially while still in the husk).

from From Malay 'padi,' meaning rice plant or rice in the husk, which English picked up during colonial trade across Southeast Asia. The English 'rice paddy' is technically a doubling — saying 'rice rice field' — but no one minds. Note this is a different word entirely from 'paddy' meaning a fit of temper (that one comes from the Irish name Patrick), and from 'paddy wagon'; the rice sense traveled by ship from the Malay-speaking world, not from Ireland.
