What does flinty mean?
"Flinty" is an adjective describing something hard, sharp-edged, and unyielding like the stone it takes its name from: flint. In its literal sense it appears in descriptions of ground and geology — farmers may speak of flinty soil that blunts ploughshares, and wine writers prize the mineral character that flinty terrain can impart to grapes. More often, however, the word carries a figurative force, applied to people and their demeanour: a flinty stare, flinty resolve, or flinty pragmatism all suggest sternness, self-discipline, and an absence of sentiment. The connotation is usually of toughness that commands respect rather than mere coldness, though context can tip it toward severity. The word derives simply from flint plus the suffix -y, and its enduring usefulness lies in this vivid concreteness — by borrowing the name of one of nature's hardest stones, "flinty" lets writers characterise human firmness with a single, striking image.
Composed of or resembling flint; extremely hard and stony.
"The path was littered with flinty fragments that cut our boots."
Most common in geological, agricultural, and viticultural contexts.
(Of a person or their expression) sternly unyielding; showing no warmth or emotion.
"He answered every question with a flinty calm."
The dominant sense in modern figurative usage; usually denotes admired toughness rather than simple cruelty.
"Flinty" literally means made of flint — so when you call someone's gaze flinty, you're saying their eyes are as hard as the stone that sparked humanity's first fires.

Etymology of flinty
"Flinty" was formed in English from the noun "flint" combined with the suffix -y, first appearing in written English around the late sixteenth or early seventeenth century. The underlying word "flint" is ancient, traceable through Old English "flint" back to Proto-Germanic origins shared with related Germanic forms such as Dutch "vuursteen" traditions of fire-stone naming. The figurative sense, describing a person's hard or stern character, developed naturally out of the stone's well-known hardness and its use as a fire-starter, giving the word its dual life describing both actual rock and unyielding temperament.
