What does blunt mean?
Blunt is most commonly an adjective describing either a physical edge that has lost its sharpness — a blunt knife cannot slice cleanly — or a manner of speaking that is strikingly direct. A blunt remark states the truth plainly, sometimes so plainly that it borders on rudeness; a blunt person does not soften opinions to spare feelings. The word can also function as a verb, meaning to dull an edge or to deaden a sensation or effect, as when painkillers blunt the symptoms of an illness. As a noun it denotes a medical needle with a rounded tip, and in informal usage, especially in American English, a cigar filled with marijuana. Derived forms such as 'bluntly' and 'bluntness' are frequent in both everyday and formal writing. Because it captures the tension between honesty and tact, blunt is a useful word for describing communication styles with precision.
(Of an edge or point) not sharp enough to cut or pierce effectively; (of speech or manner) direct and plain, often to the point of appearing tactless; (of a feeling or impact) dulled or weakened.
"After years of use, the scissors were too blunt to cut paper cleanly."
To make something less sharp, or to reduce the force or intensity of a feeling, sensation, or effect.
"The medication blunted his appetite within days."
A short needle or instrument with a rounded tip, used especially in medicine; in slang, a cigar filled with marijuana.
"The nurse drew the blood sample using a blunt rather than a standard needle."
In informal American English, 'a blunt' very commonly refers to a marijuana cigar; context usually makes the intended sense clear.
Applies only to the noun senses: the medical instruments or, informally, the cigars.
"The surgical tray held several sterile blunts alongside the sharper needles."
The phrase 'a blunt instrument' has become political shorthand for any policy so heavy-handed it causes collateral damage along the way.

Etymology of blunt
Blunt appeared in English in the late Middle English period, first attested around the fourteenth century. Its ultimate origin is uncertain, though it is widely thought to derive from a Scandinavian source, and it may be connected to Old Norse 'blundr', a term associated with drowsiness or nodding — a link that would fit the idea of a dulled or numbed edge. The same Scandinavian root is often cited as a possible relative of 'blunder'. The word settled into English with its two core senses of physically dull-edged and figuratively plain-spoken by the early modern period.

The adverb 'bluntly' often introduces an uncomfortable statement ('To put it bluntly…'). In British English, 'blunt' is also common slang for a cannabis cigarette, a usage now widespread elsewhere.
