Exercises on adjectives for 6th grade

Indicate the alternative in which the word in bold is an adjective.

Answer key explained

Adjectives express characteristics of something or someone. In this case, the official word is characterizing the document.

In alternative b) the word "official" is not presenting a characteristic, therefore, it is not an adjective. In this case, it is a noun, because it is giving a name to a being.

c) The parade carnivalesque attracted thousands of revelers to the streets.

a) turquoise blue, emerald green, olive green

b) dark brown, political-social, light green

Answer key explained

When both words are adjectives, only the last one goes into the plural, with the exception of the compound adjective deaf-mute, in which both make plural: deaf-mute.

As for the remaining alternatives:
