Origin & History of “yawn”
Yawn goes back ultimately to the Indo-European base *ghei-, *ghi-, which also produced Greek kháskein ‘gape’ (a close relative of English chasm (17th c.)) and Latin hiāre ‘gape, yawn’ (source of English hiatus (16th c.)). The base passed into prehistoric Germanic as *gai-, *gi-, whose surviving descendants are German gähnen, Dutch geeuwen, and English yawn. English gap and gape probably come from an extension of the same Indo-European base.
