Q. Do you need to use two indefinite articles with coordinate nouns when one noun begins with a vowel sound and the other begins with a consonant sound? For example, “walking the halls of an elementary or [a] secondary school.” Is the a before secondary required? Would the same be true for coordinate adjectives? For example, “including a relatable and [an] encouraging teacher”? Is the an required?
A. The second article is not required. Readers will mentally supply it.
