Loot (n.)

Thugs (n.)
The word “Thuggee” derives from the Hindi ठग (ṭhag), which means “deceiver”. Related words are the verb thugna (“to deceive”), from the Sanskrit स्थग (sthaga “cunning, sly, fraudulent”) and स्थगति (sthagati, “he conceals”).[5] This term, describing the murder and robbery of travellers, is popular in South Asia and particularly India.  Thuggee or tuggee (Hindi: Nepali ठग्गी ṭhaggī; Urdu: ٹھگ‎; Sanskrit: sthaga; Sindhi: ٺوڳي، ٺڳ‎; Kannada: ಠಕ್ಕ thakka) refers to the acts of Thugs, an organised gang of professional robbers and murderers. Thugs travelled in groups across South Asia for six hundred years.[1] Although the Thugs traced their origin to seven Muslim tribes, Hindus appear to have been associated with them at an early period.
