(1) Partly from Middle English yanen ‘to yawn’, from Old English ġānian, from Proto-Germanic *ganōnan (cf. North Frisian jåne, German gähnen, Swedish dialect gana ‘to gape, gawk’), denominative of *ganaz (cf. Swedish gan ‘gullet, maw’); (2) and partly from Middle English yenen, yonen ‘to yawn’, from Old English ġinian, ġionian, frequentative of ġīnan, from Proto-Germanic *gīnanan (compare Norwegian gina ‘to gape’), from Proto-Indo-European *ǵʰih₁-neh₂ (compare Russian зинуть (zínutʹ), Greek χαίνω (chaínō)); (3) both from *ǵʰeh₂u- ‘to yawn, gape’ (compare Dutch geeuwen, Latin hiō, Tocharian A śew, Tocharian B kāyā, Lithuanian žióti, Russian зиять (zijátʹ), Sanskrit vijihite).

  • This surprised me:

    "Yawning, argues Dr. Robert Provine, a neuroscientist, professor of psychology, and yawning expert (yes, yawning expert) at the University of Maryland, Baltimore County, is an evolutionary trait conserved across all vertebrate species. Fish do it, lions do it, we do it. It is so embedded in the primitive parts of our brains that fetuses do it in utero."
