چ che or chīm, called also jīm-i-fārsī or jīm-i-aﻌjamī, the seventh letter of the Persian alphabet, sounds like ch in the English word cheek. It does not occur in Arabic. If used to denote a number, according to the abjad, it stands for 3, like ج (jīm). The permutations of the letter چ are the following; into ژ as کاژ for کاچ Glass, a pine tree; into ز as پزشک pizishk for پچشک pichishk, A physician or apothecary; into ش as کاشي for کاچي Made of glass; into ج as کاج for کاچ; and, arabistically, into ص as صين for چين China. This letter corresponds to च in Sanskrit, and when aspirated, or with ه affixed, to छ.
