the word 'tandoori' entered english in the 20th century, directly from hindi and urdu, to describe a specific south asian cooking method. its core, 'tandoor', refers to the distinctive cylindrical clay oven used for baking bread and roasting meats, a culinary technology with ancient roots. the term's lineage extends through persian 'tanūr' back to akkadian 'tinūru', connecting it to a very old near eastern tradition of oven construction. in english, the suffix '-i' is treated as an integral part of the borrowed adjective, which now globally signifies food, especially chicken, characterized by its unique preparation in a tandoor and its associated marinades and flavors.

this word is a loanword from hindi and urdu, adopted as a simplex form in english. it is derived from the hindi/urdu word 'tandūrī', which is an adjective formed from 'tandūr', meaning a clay oven. 'tandūr' itself has persian origins, from 'tanūr', and can be traced back to the akkadian word 'tinūru', meaning 'fire' or 'oven'. its functional role in english is as a monomorphemic adjective.
