The word "determinant" traces back to Latin determinare ("to limit, settle"), combining de- (completely) + terminare (to bound, from terminus "boundary"). The morpheme "min" reflects the Latin root minuere ("to lessen"), suggesting a narrowing down to decisive factors. Over time, it evolved in mathematics (18th century) to denote a value that "determines" properties of a matrix. The suffix "-ant" marks it as an agent noun or adjective.
