From Middle Persian [Term?] (/⁠tārīk⁠/), from [Term?] (/⁠tār⁠/, “darkness”), Northern Luri تێریک (tırik), ultimately from Proto-Indo-European *témHos (whence modern تار (târ, “dark, faint”)), + Middle Persian [Term?] (/⁠-īk⁠/, adjective-deriving suffix) (whence modern ـی (-i)). One of a few adjectives that has preserved the final -g/k phoneme and did not undergo the regular sound change from Middle Persian to Modern Persian. Others include باریک (bârik, “slender”) and نزدیک (nazdik, “near”).
