The word 'tagine' is a direct borrowing from French, which itself adopted it from the Arabic 'ṭājin', derived from the Greek 'tágēnon', meaning 'frying pan' or 'shallow pot'. This Greek term is believed to have originated from the Persian 'tāva', meaning 'pan'. The culinary journey of the word mirrors the historical trade and cultural exchange across the Mediterranean and North Africa, where the cooking vessel and its associated dish became iconic. In English, the term first referred specifically to the distinctive pot before becoming a metonym for the dish cooked within it, encapsulating both the tool and the traditional meal in a single lexical item.

This word is a loanword from a foreign language and is not productively formed from separable English morphemes. It is treated as a simplex unit in English.
