I bet you didn’t know that there is a certain order in which to put multiple adjectives describing the same thing.
Native English speakers do it without thinking about it, but for those people learning English as a second or third language, we should define the proper order.
We admire “your shiny new red car” and not “red new shiny your car.”
Here is the official order of priority:
#1 = Determiner – definite or indefinite articles and possessives
Examples: the office, your boss
#2 = Observation or opinion
Examples: interesting comment, expensive valve
#3 = Size and shape
Examples: round, three-inch
#4 = Age
Examples: new, five-year-old
#5 = Color
Examples: mottled, red
#6 = Origin
Examples: British, home-made
#7 = Material
Examples: stainless steel, limestone
#8 = Qualifier, often an integral part of the noun
Examples: ball valve, drilling rig
Thus, “your shiny new red car” would be a 1-2-4-5 car, obeying the Royal Order.
We usually put commas in between multiple adjectives in a row, unless the words are really short and string together nicely like the shiny new red car (we wouldn’t say “shiny, new, red car”).
Their reliable, four-inch, used, purple, Swedish, stainless steel butterfly valve is a 1-2-3-4-5-6-7-8.
And so are her delicious, big, annual, decorated, home-made, gingerbread Christmas cookies.
