pinch

the word 'pinch' has a somewhat obscure but expressive lineage. it likely emerged in middle english from the verb pinchen, which may have blended with the old french pincier. both sources are thought to ultimately derive from a vulgar latin base pinctiare, meaning 'to prick', or possibly be of onomatopoeic origin, imitating the action or sound of a sharp nip. the core action of squeezing tightly between fingers and thumb has remained remarkably consistent. over time, its meaning expanded metaphorically to describe any constrictive pressure, as in tight shoes, and by the 16th century, it acquired the quantitative sense of a very small amount, literally what one can hold between a pinch of fingers.

this word is a simplex form. it is of uncertain origin, possibly from a blend of middle english pinchen (to pinch) and old french pincier (to pinch), both of which are likely of vulgar latin or imitative origin.
