  • Do not confuse with 'клык' (canine tooth). 'Incisor' is specifically 'резец'.
  • The word is a noun; no direct verb form exists in English unlike some Russian constructions.

Common Mistakes

  • Mispronunciation: stressing the first syllable (IN-sisor) instead of the second (in-CISE-or).
  • Using 'incisor' as a verb (e.g., 'to incisor' is incorrect).
