Use commas
Between two or more consecutive adjectives*
- the fast, powerful computer
- the complicated, inefficient code
- Don’t use commas if first adjective modifies second adjective rather than noun
- traditional political institutions
- Don’t use commas if adjectives refer to size or age
- little old lady
- large red-haired girl
*Tip: If adding “and” between the adjectives makes sense, add commas
