What does brute mean?
A brute is, most commonly, a cruel or violently aggressive person — someone who behaves like an animal rather than a reasoning human. The word also refers simply to non-human animals ('the brutes'), especially in older or more formal writing. As an adjective, 'brute' describes something that relies on raw physical power or mechanical repetition rather than intelligence: we speak of 'brute strength', 'brute force', and, in computing, the 'brute-force attack', where every possible password or key is tried until one works. The word derives from the Latin brutus, meaning 'dull' or 'unreasoning' — the same root that gives us 'brutal' and 'brutality'. Connotations are almost entirely negative when applied to people, suggesting coarseness, insensitivity, and lack of self-control. Despite this, its adjectival uses remain vigorous and neutral in tone across technical writing, sport, and everyday description, making 'brute' a word whose meaning depends heavily on context.
A cruel, violent, or insensitive person; alternatively, an animal as opposed to a human being.
"He was a brute who terrorised everyone in the household."
When used of people, always pejorative and often suggests physical menace.
Relating to or involving only physical strength or mechanical process, without intelligence, refinement, or reason.
"They broke down the door through sheer brute force."
Most common today in fixed phrases such as 'brute force' and 'brute strength'; also used technically in computing and philosophy.
Standard plural; common in phrases like 'the brutes of the field' referring collectively to animals.
"In the old bestiaries, lions were described as noble among all the brutes."
The word 'brute' comes straight from the Latin for 'stupid' — so calling someone a brute is literally calling them senseless.

Etymology of brute
Brute entered English in the late Middle Ages from Old French, ultimately deriving from the Latin brutus, meaning 'heavy, dull, stupid, or irrational'. The Latin adjective famously became the cognomen of Marcus Junius Brutus, Caesar's assassin, though the English word traces to the general Latin term rather than the family name. From the same root come 'brutal', 'brutish', and 'brutality'. The word originally referred specifically to animals as unreasoning creatures, before extending by metaphor to humans who behaved like them.

How brute is actually used
As a noun applied to people, 'brute' carries strong negative connotation and is somewhat dated in everyday speech but still common in literature and journalism. The adjectival uses 'brute force' and 'brute strength' are very much alive, especially in computing (where 'brute-force attack' means trying every possibility systematically) and in describing physical labour. 'Brute fact' is a term in philosophy for a fact that admits no further explanation.
Easily confused with brute
