Onomatopoeia
Words that imitate the sound they describe
Onomatopoeia is a type of word, or the process of creating a word, that phonetically imitates, resembles, or suggests a sound that it refers to. Common onomatopoeias in English include animal noises such as oink, meow, roar, and chirp, among various other noise-based verbs and nouns such as beep, simmer, or hiccup. Among the many words that likely began as onomatopoeias but whose original expressive iconicity goes unrecognized by modern speakers, examples include fanfare, pigeon, and cough.
