Most native speakers of English will instinctively agree the order of the adjectives in my sentence above is wrongâweird evenâwithout necessarily being able to describe exactly why; it flouts some rules that we all know but are not normally conscious of. These rules are difficult to write down precisely but roughly speaking follow a sort of semantic spectrum. The Cambridge Dictionary gives this order
opinion - size - physical nature - shape - age - colour - origin - material - type - purpose
If we rewrite my initial sentence using this order we get
my lovely big fat new red hardback grammar book
which sounds perfectly normal, albeit a bit wordy perhaps.
Mu new dictionaryâthe one picturedâcalls the rules "Adjectival order", although "Royal Order of Adjectives" is a more colourful name.Â
