Running in front, sneak a look round (6)
I believe the answer is:
upkeep
'running' is the definition.
(thesaurus)
'front sneak a look round' is the wordplay.
'front' becomes 'up' (I can't explain this - if you can you should believe this answer much more).
'sneak a look' becomes 'peek' (I've seen this in another clue).
'round' says the letters should be written backwards.
'peek' in reverse letter order is 'keep'.
'up'+'keep'='UPKEEP'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for upkeep that I've seen before include "Running costs" , "Cost of support" , "Looking after" , "Peek up at the maintenance" , "payments?" .)
