All but one in football team fit and sound? (7)
I believe the answer is:
tenable
'sound?' is the definition.
(both can mean solid or viable)
'all but one in football team fit' is the wordplay.
'all but one in football team' becomes 'ten' (I can't justify this - if you can you should believe this answer much more).
'fit' becomes 'able' (similar in meaning).
'ten'+'able'='TENABLE'
'and' is the link.
Can you help me to learn more?
(Other definitions for tenable that I've seen before include "Able to be held" , "fairly arguable" , "Possible to be defended" , "okay as regards defence" , "possible to maintain" .)
