Errores habituales de los hispanohablantes

Spanish speakers sometimes make a few common mistakes with English numbers 1-12, mainly with pronunciation.

  • The 'th' sound in three: This sound does not exist in Spanish. Many learners pronounce it like an 'f' or a 't'.
    • Incorrecto: tree (sounds like a plant)
    • Correcto: three (tongue between teeth, blowing air)
  • The 'v' sound in five y seven: In Spanish, 'v' often sounds like 'b'. In English, 'v' is pronounced with your top teeth on your bottom lip.
    • Incorrecto: bive (for five)
    • Correcto: five
  • Confuso nine y ten: Practice these two carefully to avoid mixing them up.
    • nine (ends with 'n' sound)
    • ten (ends with 'n' sound, but a distinct 't' at the start)
