Exposed, say, climbing the far boundary (7)
I believe the answer is:
outedge
'exposed say climbing the far boundary' is the definition.
I can't tell whether this definition defines the answer.
'exposed say climbing' is the wordplay.
'exposed' becomes 'outed' (to out someone is to expose them).
'say' becomes 'eg' (both can mean for example).
'climbing' is a reversal indicator (in a down clue, letters climb up).
'eg' back-to-front is 'ge'.
'outed'+'ge'='OUTEDGE'
Can you help me to learn more?
(Another definition for outedge that I've seen is " furthest limit".)
