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 ( or ) or a laryngeal ( or ), 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: and ( denoting a vowel and a long vowel). Often the rules and also are added.
