imperil

The word 'imperil' is a relatively modern English formation, constructed by combining the Latin-derived prefix 'im-' with the existing English noun 'peril'. The noun 'peril' itself has a long history, entering Middle English from Old French 'peril', which descended from Latin 'periculum' meaning "trial, risk, danger." The Latin term is thought to be derived from the root 'per-' (to try, risk), which is also seen in words like 'experience'. Therefore, the literal construction of 'imperil' is "to put into danger," a meaning that has remained transparent and unchanged since its formation. It serves as a more formal or literary synonym for the verb 'endanger'.
