طفيل

Etymology
Diminutive of, though in the sense of “parasite” perhaps a backformation from the commoner adjective. Ancient Arabic lexicographers explained this sense as being derived from the name of a certain man called Ṭufayl, who, among the ancient Arabs, used to gatecrash feasts. However, a derivation directly from the diminutive sense might also make sense. 🇨🇬 is a 19th-century invention based on the Arabic word.
