Cardinal Numbers: Counting from 1 to 100 in Portuguese

Grammar Rule in 30 Seconds

Portuguese cardinal numbers 1-100 follow specific gender rules for 'one' and 'two', while others remain invariant.

  • The numbers 'um' (1) and 'dois' (2) change gender to match the noun: 'um carro' vs 'uma casa'.
  • Numbers from 21 to 99 use the conjunction 'e' to connect tens and units: 'vinte e um'.
  • Numbers 16-19 are formed by adding 'dez' (10) to the unit: 'dez' + 'seis' = 'dezesseis'.
Number + Noun (e.g., 3 + maçãs = três maçãs)

مرور کلی

Portuguese numbers 1-20 must be memorized. From 21 on, combine with e (and): vinte e um (21), trinta e dois (32). Hundreds agree in gender: duzentos/duzentas. Note: 1 and 2 have gender forms: um/uma, dois/duas.
