Etymology
The word grows from the Arabic root ث-ل-ث, tied to the number three (ثَلَاثَة, thalātha). Adding the nisba suffix -iyy, the ending that turns a noun into a relational adjective, produces ثُلاثِيّ, meaning of or pertaining to three parts. This same root gives Arabic grammar its term for the three-letter verb and noun patterns that form the core of the language's word structure.
