thug

Three meanings in use today

1. A violent, brutish criminal, or a bully. The everyday sense, and the one Merriam-Webster lists first.4Two thugs waited by the car.
2. One of the strangler gangs of India. Merriam-Webster’s second sense: a member of a group of murderous robbers in India’s past whose activities were suppressed in the early 19th century. Wiktionary labels it historical.46Colonial officers hunted the thugs of central India in the 1830s.
3. A plant that takes over a bed. Wiktionary lists a gardening sense: an overvigorous plant that spreads and dominates the flowerbed.6The mint turned into a thug and crowded out the roses.

Words people mix up with it

thuggee

The practice, not the person: the system of ritual killing the gangs were said to follow. Etymonline gives thuggery as 1839 and thugee as the form closer to the Hindi.3

phansigar

The other Indian name for the gangs, “strangler”, from phansi, “noose”. Hobson-Jobson says it was their proper designation.23

goon, hoodlum, ruffian

Merriam-Webster’s thesaurus lists them as near synonyms for the criminal sense.5

gangster

The first synonym Merriam-Webster’s thesaurus gives for the criminal sense.5

What the word meant, year by year

Dictionaries say 1810 or 1839. The word started as plain Hindi for a cheat, became the name of the gangs by 1810, and by 1839 was an English word for any hard man. Drag the line and read what people wrote.

From a word for cover to a word for crime

1. *(s)teg-Proto-Indo-European, “to cover”. Etymonline lists deck and detect among its English descendants.3
2. sthagaSanskrit, “cunning, fraudulent”, from sthagayati, “(he) covers, conceals”. Etymonline says “perhaps”.3
3. thag, thakHindi and Marathi, “cheat, swindler”.32
4. phansigarThe other name for the gangs, from phansi, “noose”.2
5. ThugEnglish, as the name of the gangs by 1810, and as a general word for a ruffian by 1839.3

The stops mark central India, where the gangs were hunted, and London, where the book on them was printed. Nobody documented a single journey for the word. Wiktionary traces it to Prakrit and calls the earlier origin uncertain.6

Why dictionaries date it differently

You get 1808, 1810 and 1839, and all three can be right, because the word had three jobs.

Hobson-Jobson dates the cheat sense earliest, and doesn’t say whether Drummond’s word was the same one that became the gangs’ name. We read that book only through Hobson-Jobson, and Etymonline gives no text for 1810.

The Kali death cult

• The story was told that way at the time. Macaulay in 1843 spoke of the Thugs acting under the special protection of the most powerful goddesses.2 The Century Dictionary, quoted by Etymonline, says a third of their spoil went to Kali, whom they worshiped.3
• The oldest accounts we could read don’t mention a goddess. The passages Hobson-Jobson quotes from Fryer in 1673 and Forbes in 1785 describe gangs strangling travelers with a cord, and say nothing about religion.2
• Modern historians have taken the cult apart. Wikipedia’s summary says Kim Wagner calls the Thugs “no more than a species of robber” and the 1830s a moral panic, while Mike Dash finds the motives not religious and the beliefs closer to folklore than a faith. Dash puts the dead at 50,000 to 100,000, colonial estimates went as high as a million, and the testimony of Thugs who turned informer rarely mentions Kali. Wagner also says the colonial picture wasn’t invented from nothing.10

We haven’t opened Wagner’s book (Thuggee: Banditry and the British in Early Nineteenth-Century India, 2007) or Dash’s, only the summary in Wikipedia, so treat the numbers as theirs, not ours.10

The word, measured

Psychologists have asked thousands of people about tens of thousands of words. Here is where thug lands in six of those datasets.

Ratings come from panels of roughly 20 to 30 people per word, asked about the word out of context. Percentages are how thug ranks among the words in that dataset.

Its relatives, and a few impostors

thuggery

In English from 1839, first as “the system of ritual killing as practiced by the thugs”.3

thuggee

The form closer to the Hindi name for the system. Also spelled thugee.3

thuggish

“Ruffianly, brutal and forceful”, from 1870.3

phansigar

The “stranglers”, from phansi, “noose”.23

deck, detect

Etymonline lists them under the Proto-Indo-European root for “cover”, and Wiktionary says thug is perhaps related to deck and thatch.36

Spin-offs

Wiktionary lists thug life, thugdom, thugocracy and cyberthug among the English words built on it.6
