Each week the man runs with energy far and wide (10)
I believe the answer is:
everywhere
'far and wide' is the definition.
(synonyms)
'each week the man runs with energy' is the wordplay.
'each' becomes 'every' (synonyms).
'week' becomes 'w' (abbreviation).
'the man runs with' becomes 'her' (I can't explain this - if you can you should give a lot more credence to this answer).
'energy' becomes 'e' (physics symbol as in E=mce).
'every'+'w'+'her'+'e'='EVERYWHERE'
Can you help me to learn more?
(Other definitions for everywhere that I've seen before include "In all places" , "rife" , "All over the place" , "common" , "commonplace" .)
