A cicada; an insect with transparent wings that produces loud buzzing or chirping sounds, especially in summer.
From Latin 'cicada,' probably imitating the insect's sound. The word exists in most European languages with similar forms, showing ancient roots in Mediterranean observation of nature.
Cicad is an archaic or variant form that shows how the same insect word bounced around Europe—Latin speakers heard 'cicada-cicada' and just named it after the sound it made, one of the best examples of onomatopoeia in animal names.
