Here is the most common order of adjectives in English, though the order of adjectives of size, shape, age and colour can change:

1. Variation is possible when we focus on a particular feature:

• a round black shape ( = normal order)
• a black round shape ( = focus on colour)

2. We use a comma when there are two or more adjectives of equal importance before a noun:

• The room was full of cold, hungry children.

3. We link the adjectives with and when they come after verbs like be and feel:

• He was tall, dark and handsome.
• He was tall, dark, handsome.
• The children felt cold and hungry.
• The house was large and impressive.

4. We can put a comma or and between two adjectives that describe someone's character:

• We had a clever and imaginative teacher.
• We had a clever, imaginative teacher.

5. When we use two or more colour adjectives before a noun, we put and between them:

• They own a red and white car.
• They were waving a blue, white and red flag.
• They were waving a blue, white, red flag.
