The PIE 'yawn' verb had a "long diphthong" root, *g^He:(i)-/*g^Hi:- in
Brugmannian terms. Depending on how one analyses such roots in laryngeal
terms, the reconstruction is either *g^Heh1i- or *g^Heih1- (I favour the
latter, but the former is regarded as more orthodox nowadays). Gk.
kHasko:, however, is possibly an unrelated lookalike (from something
onomatopoeic like *gHa(:)n-).

The root is *h1erh2- (Gk. eramai 'desire, love', adj. eratós 'desired,
loved). The -s- stem nouns in Gk. must originally have been neut. *eras,
anim. *ero:s (*h1érh2-e/os-), as demonstrated by further derivatives
like <erannós> 'lovely' from *eras-no-. The t-stem (ero:t-) is either a
Greek innovation (more likely) or a trace of PIE *-s-/*-t- alternation
in s-stems.
