Big numbers
The hundreds
When you've learnt cien, 100, the rest of the big numbers follow in a fairly regular pattern.
100 cien
200 doscientos
300 trescientos
400 cuatrocientos
500 quinientos - this is a bit of a tricky one
600 seiscientos
700 setecientos - a slight change: you drop the i from siete
800 ochocientos
900 novecientos - another slight change: nueve becomes nove
More than one hundred:
Numbers start with ciento:
101 ciento uno
102 ciento dos, etc.
So 123 is ciento veintitrés; and 190 is ciento noventa
Higher numbers:
201 doscientos uno
305 trescientos cinco
520 quinientos veinte, etc.
When the things you are counting are feminine, there is a feminine form:
Doscientas botellas Two hundred bottles
Thousands are even easier:
1.000 mil
2.000 dos mil
3.000 tres mil
100.000 cien mil
Millions are similar to English:
1.000.000 un millón
5.000.000 cinco millones
Note, however, that the dot, not the comma, is used to separate the thousands.
