Many are in good time, obviously (7)
I believe the answer is:
clearly
'obviously' is the definition.
(thesaurus)
'many are in good time' is the wordplay.
'many are' becomes 'cl' (I can't explain this - if you can you should believe this answer much more).
'in good time' becomes 'early' (being early is arriving in good time).
'cl'+'early'='CLEARLY'
Can you help me to learn more?
(Other definitions for clearly that I've seen before include "Without doubt or question" , "Obviously; with clarity" .)
