Dinosaur Audio Guide: Adjective Commas

Edit descriptive language for a museum recording.

1. Test the Adjective Pairs

Choose the best answer for each script excerpt. Judge the punctuation, not the pauses a narrator might make.

A museum team is preparing a dinosaur audio guide. Coordinate adjectives describe a noun independently. They usually make sense with and between them and in reversed order: a clear, accurate description. Cumulative adjectives build a description together: two large footprints. Do not separate cumulative adjectives with a comma, and do not put a comma between the final adjective and its noun.

A. Examine the rough, uneven, surface.B. Examine the rough, uneven surface.C. Examine the rough uneven, surface.D. Examine the rough uneven surface.

The draft says, “Follow the narrow stone path to the footprint exhibit.” Why is there no comma between narrow and stone?

A. Stone is the noun that narrow describes in this sentence.B. Short adjectives do not need commas between them.C. Adjectives before path cannot be separated by commas.D. Narrow describes the stone path as a single unit.

A. Both adjectives have several syllables when spoken aloud.B. The noun introduction comes after both descriptive words.C. Both dramatic and memorable and memorable, dramatic make sense.D. The narrator could pause after either descriptive word.
