What it means
محیط زیست (mohit-e zist) means the environment, in the ecological and policy sense of the word. It is a compound: محیط (mohit) comes from Arabic مُحِيط (muhīt), meaning surroundings or milieu, while زیست (zist) is pure Persian, derived from زیستن (zistan, to live). Together they form a calque meaning something close to living surroundings. The term is the standard formal phrase in Iranian environmental law, journalism, and academia. The government agency responsible for environmental protection is called سازمان حفاظت محیط زیست (Sâzmân-e Hefâzat-e Mohit-e Zist), the Department of Environment of Iran. In casual speech, Iranians sometimes shorten the phrase to simply محیط (mohit) when the context is clear.
How to use it
- باید از محیط زیست حفاظت کنیم. (Bâyad az mohit-e zist hefâzat konim.) “We must protect the environment.”
- آلودگی به محیط زیست آسیب میزنه. (Âludegi be mohit-e zist âsib mi-zane.) “Pollution damages the environment.”
- محیط زیست ایران در خطره. (Mohit-e zist-e Irân dar khatare.) “Iran’s environment is at risk.”
- تو درس محیط زیست داریم. (Tu dars-e mohit-e zist dârim.) “We have an environmental science class.”
Cultural note
Environmental awareness became a formal policy concern in Iran from the 1970s onward, and the phrase محیط زیست entered common usage alongside that shift. Iran faces serious environmental challenges including the shrinking of Lake Urmia, chronic air pollution in Tehran, and desertification in central provinces, and محیط زیست appears daily in news coverage of these issues. The compound also illustrates a productive pattern in modern Persian: pairing an Arabic noun with a Persian gerund or verb root to name new concepts, a strategy that avoids full borrowing while still drawing on the Arabic lexical heritage that is deeply embedded in the language.
