Native speakers of a language usually use adjectives in the correct order, but what if you are trying to explain the rule to a non-native speaker. It turns out that adjectives in English must be in this order: opinion-size-shape-colour-origin-material-purpose Noun.
You can have a charming, little, old, rectangular, brown, pioneer, wooden butter churn. But if you mess with the order, it’ll sound weird. Try forming your own adjective collection in a sentence – just don’t ever use that many adjectives together in your writing!
Most English speakers automatically use the list, but almost none of us could write out the rule.
