Erreurs courantes chez les hispanophones

A common mistake for Spanish speakers is trying to translate numbers directly. For example, saying ten and one instead of eleven. Remember that eleven, twelve, et twenty are unique words in English.

Another mistake is confusing the -teen sound (like in thirteen) with the -ty sound (like in thirty). For numbers 13 to 19, always use -teen. Pay attention to the stress in words like thirteen (stress on ‘teen’) versus thirty (stress on ‘thir’).

Questions fréquemment posées

Why are ‘eleven’ and ‘twelve’ special?

Numbers eleven et twelve are special because they do not follow the -teen pattern. They have their own unique names, just like one to ten.

How can I remember the ‘teen’ numbers?

Numbers from thirteen to nineteen all end with -teen. You can think of it like ‘ten plus three’ becomes thirteen. This pattern helps you remember them.

Are numbers 11-20 used often in English?

Yes, numbers 11 to 20 are used very often in daily English. You need them for counting, telling age, giving phone numbers, and many other common situations.
