regret

The word 'regret' has a poignant journey, entering Middle English from the Old French regreter, which carried the sense of lamenting or mourning a loss. Its ultimate roots are murky but point to a Germanic source, likely connected to words for weeping and audible grief, such as the Old Norse grāta. This etymological path suggests that the core concept was originally an outward expression of sorrow. Over time, the meaning evolved inwards, shifting from a vocalized lament to the internal, reflective feeling of sadness or disappointment over past actions or events that characterizes its modern usage.

The word is a simplex form. It entered English from Old French regreter, meaning "to lament, bewail, long after." The Old French term is of uncertain origin but is likely Germanic, possibly related to Old Norse grāta ("to weep, groan") or Frankish grētan ("to weep").
