Strip edges off by way of technicalities (6)
I believe the answer is:
trivia
'way of technicalities' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'strip edges off by' is the wordplay.
'strip edges off' becomes 'tri' (I can't explain this - if you can you should believe this answer much more).
'by' becomes 'via' (I've seen this in other clues).
'tri'+'via'='TRIVIA'
Can you help me to learn more?
(Other definitions for trivia that I've seen before include "Non-essential data" , "Inconsequential facts" , "The details of little or no importance" , "Useless facts" , "useless bits of information?" .)
