Stang's law is a Proto-Indo-European (PIE) phonological rule named after the Norwegian linguist Christian Stang. The law governs the word-final sequences of a vowel, followed by a semivowel (*y or *w) or a laryngeal (*h₁, *h₂ or *h₃), followed by a nasal. According to the law these sequences are simplified such that laryngeals and semivowels are dropped, with compensatory lengthening of a preceding vowel.
This rule is usually cited in more restricted form as: *Vwm > *Vːm and *Vh₂m > *Vːm (*V denoting a vowel and *Vː a long vowel).
Often the rules *Vmm > *Vːm and also *Vyi > *Vːy are added:[1]
- PIE *dyéwm 'sky' (accusative singular) > *dyḗm > Sanskrit dyā́m, acc. sg. of dyaús, Latin diem (which served as the basis for Latin dies 'day'), Greek Zen (reformed after Homeric Greek to Zena), acc. of Zeus
- PIE *gʷowm 'cow' (acc. sg.) > *gʷōm > Sanskrit gā́m, acc. sg. of gaús, Greek (Homeric and dialectal) bṓn, acc. sg. of bous 'cow'
- acc. sg. of PIE *dom- 'house' is *dṓm, not **dómm̥.
- acc. sg. of PIE *dʰoHn-éh₂ 'grain' after laryngeal colouring is the disyllabic *dʰoHnā́m, not trisyllabic **dʰoHnáh₂m̥ > **dʰoHnā́m̥
