Working playwright, reportedly -- not in the main?
I believe the answer is:
onshore
'reportedly not in the main?' is the definition.
I can't tell whether this definition defines the answer.
'working playwright' is the wordplay.
'working' becomes 'on'.
'playwright' becomes 'shore' (I can't explain this - if you can you should believe this answer much more).
'on'+'shore'='ONSHORE'
Can you help me to learn more?
(Other definitions for onshore that I've seen before include "coming in from water" , "towards the coast" , "Occurring on land" , "beach?" , "(Of wind) blowing from sea" .)
