Might accost lyricist, making them reveal how overpriced they are (6)
I believe the answer is:
costly
'how overpriced they are' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'might accost lyricist making them' is the wordplay.
'COSTLY' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
'reveal' acts as a link.
Can you help me to learn more?
(Other definitions for costly that I've seen before include "Dear" , "High-priced" , "Expensive" , "Highly priced" , "Entailing great loss or sacrifice" .)
