Attributive adjectives always come directly before the noun they describe in English. In 'the blue sky,' 'blue' is attributive to 'sky.'
Pro Tip 2/3
Adjectives Only
'Attributive' is not for verbs or adverbs; it's specific to adjectives used with nouns. 'Big' in 'big computer' is attributive, but 'quickly' in 'runs quickly' is not.
Pro Tip 3/3
No Commas Needed
Do not use commas between attributive adjectives and the nouns they modify. We say 'a cold, dark night,' not 'a cold, dark, night.'
