Mastering them will make it easier to understand native speakers and communicate clearly in many situations. You will learn to say and spell each number, from eleven to twenty.

Erreurs courantes chez les hispanophones

Spanish speakers sometimes make small mistakes with these numbers. Here are some common ones:

  • Confusing -teen et -ty: It is easy to confuse numbers like thirteen (13) and thirty (30). Listen carefully to the end sound. Thirteen has a long ‘ee’ sound at the end. Thirty has a short ‘ee’ sound.
  • Pronouncing V dans Twelve: Make sure to pronounce the v sound clearly in twelve. It is not twel.
  • Spelling Fifteen: Remember it is fifteen, not fiveteen.
