Work discussing ten square chains becomes more baffling (7)
I believe the answer is:
opaquer
'more baffling' is the definition.
Both the definition and answer are comparative adjectives. Maybe there's an association between them I don't understand?
'work discussing ten square chains' is the wordplay.
I cannot really see how this works, but
'work' could be 'op' (abbreviation for opus) and 'op' is present in the answer.
This explanation may well be incorrect...
'becomes' acts as a link.
Can you help me to learn more?
(Other definitions for opaquer that I've seen before include "It's not so easy to grasp" , "Less clear" , "Rather obscure" , "Less transparent" .)
