Most keen to have toilets close to bidet (8)
I believe the answer is:
pottiest
'most keen' is the definition.
Both the answer and definition are superlative adjectives. Perhaps they are linked in a way I don't understand?
'toilets close to bidet' is the wordplay.
'toilets' becomes 'potties' ('potty' can be a synonym of 'toilet').
'close to' suggests the final letters (the 'close' to the word).
The last letter of 'bidet' is 't'.
'potties'+'t'='POTTIEST'
'to have' is the link.
Can you help me to learn more?
(Other definitions for pottiest that I've seen before include "Most nutty" , ""most mad"" .)
