2.58 Position of adjectives in noun groups

When you use more than one adjective in a noun group, the usual order for the adjectives is: qualitative adjectives, followed by colour adjectives, followed by classifying adjectives.

...a little white wooden house.
...pretty black lacy dresses.
...a large circular pool of water.
...a beautiful pink suit.
...rapid technological advance.
...a nice red apple.
...the black triangular fin.

This order is nearly always followed in English. Occasionally however, when you want to focus on a particular characteristic of the person or thing you are describing, you can vary this order, especially when one of the adjectives refers to colour or size.

...a square black hole.

Note that you sometimes put a comma or 'and' between adjectives. This is explained in paragraphs 8.168 to 8.174 and paragraph 8.189.

...the long, low caravan.
It was a long and tedious business.

2.59

Comparatives (see paragraphs 2.108 to 2.116) and superlatives (see paragraphs 2.117 to 2.127) normally come in front of all other adjectives in a noun group.

...better parental control.
...the highest monthly figures on record.
