Is "stress test" hyphenated when an adjective?
My question is when "stress test" is an adjective is it hyphenated?
Solution 1:
I assume you want to use it before the noun because how else would it become an adjective?
Use a hyphen in a compound modifier when the modifier comes before the word it’s modifying.
However,
Generally, you need the hyphen only if the two words are functioning together as an adjective before the noun they’re describing. If the noun comes first, leave the hyphen out.
