11 - Adjective order

Adjectives usually have an order in which they are placed, in front of a noun:

1/ determiner (eg: three, a, the, ours, etc.: although "a" and "the" are articles, not adjectives);
2/ value (eg wonderful, disagreeable, etc.);
3/ size (eg: small, large, etc.);
4/ age (20th century, new, etc.);
5/ shape (square, round, etc.)
6/ colour
7/ origin (English, Edwardian, etc.);
8/ material (iron, plastic, etc.);
9/ compound (sitting-room, etc.).
and lastly the noun.

You can change this order exceptionally, if you want to provide extra emphasis to what you are saying.
