yawn

yawn: [OE] Yawn goes back ultimately to the Indo-European base *ghei-, *ghi-, which also produced Greek kháskein ‘gape’ (a close relative of English chasm [17]) and Latin hiāre ‘gape, yawn’ (source of English hiatus [16]). 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.
=> chasm, gap, gape, hiatus
