1. He has long, straight, black hair.
2. He has straight,long, black hair.
Which one is correct? I'd like to know the word order.
Both are correct, but I'm more accustomed to hearing number 1. These adjectives are interchangeable because they all describe the hair.
Both sentences are grammatically correct. However, the word order in English typically follows the pattern of opinion, size, age, shape, color, origin, material, and purpose.
Based on this pattern, the first sentence, "He has long, straight, black hair," adheres to the expected word order. In this sentence, "long" describes the length of the hair, "straight" describes the shape of the hair, and "black" describes the color of the hair.
The second sentence, "He has straight, long, black hair," deviates from the typical word order. Although it is still grammatically correct, it might sound less natural to native English speakers who are used to the pattern mentioned above.
So, in terms of word order, the first sentence is considered more standard and commonly used.
