Are such letters read aloud? (3)
I believe the answer is:
red
'are such letters' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'read aloud?' is the wordplay.
'aloud?' indicates a 'sounds like' (homophone) clue (I've seen 'aloud' mean this).
'read' sounds like 'RED'.
Can you help me to learn more?
(Other definitions for red that I've seen before include "Warning light colour" , "Flushed" , "A colourful communist" , "Merchant flag" , "Carmine" .)
