Avoid These Mistakes When Using Cuatrocientos
Gender mismatch
Incorrect: Hay cuatrocientos personas en el estadio.
Correct: Hay cuatrocientas personas en el estadio.
Personas is a feminine noun, so the number must take the feminine ending -cientas instead of -cientos.
Spelling error
Incorrect: Necesitamos quatrocientos voluntarios.
Correct: Necesitamos cuatrocientos voluntarios.
The correct Spanish spelling begins with 'cu-' not 'qu-'; the root is 'cuatro' (four), which keeps its original spelling when combined with -cientos.
