Unacceptable mendacity? Not near the centre (8)
I believe the answer is:
outlying
'not near the centre' is the definition.
I can't tell whether this definition defines the answer.
'unacceptable mendacity?' is the wordplay.
'unacceptable' becomes 'out' (I've seen this before).
'mendacity?' becomes 'lying' (I've seen this before).
'out'+'lying'='OUTLYING'
Can you help me to learn more?
(Other definitions for outlying that I've seen before include "Away from the middle" , "On the exterior" , "Remote from the centre" , "remote area" .)
