Articulate boy to flatten bright terrace (7)
I believe the answer is:
sundeck
'bright terrace' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'articulate boy to flatten' is the wordplay.
'articulate' indicates a 'sounds like' (homophone) clue (articulated or said out loud).
'boy' becomes 'son' (synonyms).
'to flatten' becomes 'deck' (I've seen this in another clue).
'son' is a homophone of 'sun'.
'sun'+'deck'='SUNDECK'
Can you help me to learn more?
(Other definitions for sundeck that I've seen before include "Part of vessel" , "top of ship" .)
