Etymology

The word "shrill" originates from Old English scrallettan, meaning "to sound loudly or shrilly." The modern form retains the core idea of sharpness or high pitch, with the "-ill" suffix possibly serving as an intensifier. Over time, it evolved to specifically describe piercing sounds, reflecting its onomatopoeic roots in mimicking sharp noises.
