Each way, there's no trouble (4)
I believe the answer is:
ease
'no trouble' is the definition.
(I've seen this in another clue)
'each way there's' is the wordplay.
'each' becomes 'ea' (abbreviation).
'way' becomes 's' (Compass direction - South).
'there's' becomes 'e' (I can't explain this - if you can you should believe this answer much more).
'ea'+'s'+'e'='EASE'
Can you help me to learn more?
(Other definitions for ease that I've seen before include "Free from pain" , "Assuage" , "Comfort; facility" , "Freedom from discomfort or anxiety" , "Allay" .)
