As 50 per cent of building in Thames, decide on refurbishment! (4-8)
I believe the answer is:
semi-detached
'as 50 per cent of building' is the definition.
I can't judge whether this defines the answer.
'thames decide on refurbishment' is the wordplay.
'on' means one lot of letters go next to another.
'refurbishment' indicates an anagram (I've seen this in other clues).
'thames' put after 'decide' is 'decidethames'.
'decidethames' is an anagram of 'SEMI-DETACHED'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for semi-detached that I've seen is " Type of house".)
