💡 Grammar & Number Patterns

  • In Spanish, numbers from 16–19 are formed by combining “diez” (10) + y + number, but written together: dieciséis = 16.
  • From 21–29, “veinte” changes to “veinti” and is followed by the number: veintidós = 22.
  • Numbers are separate words after 30: treinta y cinco = 35.
  • 100 is “cien” by itself, but “ciento” before another number: ciento uno = 101.
