Cien, ciento and mil: the big numbers

on its own or before a noun, when more follows; the hundreds agree and three are irregular; and , never .

The short version

alone, when more follows

a hundred years
Why?

A hundred is on its own and straight before a noun, or : , . The moment a smaller number follows, it becomes : , . And never goes plural: two thousand is , not .

Cien and ciento

A hundred has two forms. Ask one question: does something smaller come after it?

After itFormExample
nothing . I count to 100.
a noun - a hundred years
or - a hundred thousand
a smaller number - 101
a smaller number - 120

One fixed phrase keeps alone: , per cent.

  • - ten per cent

The hundreds agree, and three are irregular

From two hundred, the hundreds are single words ending in -cientos, and they agree with the noun:

200 to 400500 to 700800 to 900
200 500 800 ochocientos
300 trescientos600 seiscientos900
400 cuatrocientos700

The three in bold are irregular: (not cincocientos), and .

Agreement is with the noun that follows, even with in between:

  • - two hundred years
  • doscientas - two hundred houses
  • quinientas - five hundred people
  • doscientas - two hundred thousand houses

Mil, never miles
