Pinault's law is a Proto-Indo-European (PIE) phonological rule named after the French Indo-Europeanist Georges-Jean Pinault who discovered it.

According to this rule, PIE laryngeals disappear before *y. Compare:

  • PIE *krewh̥₂s 'raw flesh; blood' > Vedic kravís, Ancient Greek κρέας (with the regular reflex of PIE syllabic laryngeal of Vedic -i- and Ancient Greek -α-)
  • PIE *krewyo- > Vedic kravyás, Lithuanian kraũjas (with no -i- in Vedic, Lithuanian with circumflex accent and not acute which would have been yielded by a laryngeal)
