tooth (English)
Where does "tooth" come from?
The English noun 'tooth' traces its lineage through Middle English 'tothe' and Old English 'tōþ'[1]. These forms descend from Proto-West Germanic '*tanþ' and Proto-Germanic '*tanþs'[1][5], which lost an original nasal consonant leading to compensatory vowel lengthening[2]. Moving further back in time, these Germanic terms ultimately derive from Proto-Indo-European '*h₃dónts' meaning 'tooth'[1][4]. This ancestral form functions as a derivative of the root '*h₃ed-' meaning 'to bite'[3]. Through this deep historical trajectory, the word shares etymological roots with numerous cognates across the Indo-European language family, including Latin 'dēns' and Ancient Greek 'ὀdούς'.
Open questions
- The reconstructed Proto-Indo-European form is traditionally linked with the root for eating, though comparative evidence from Armenian and Greek forms suggests an alternative laryngeal attribution. [3]
