Lie around, for instance, somewhere in Belgium (5)
I believe the answer is:
liege
'in belgium' is the definition.
(I know that Liege is part of Belgium)
'lie around for instance' is the wordplay.
'around' is a reversal indicator.
'for instance' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'eg' in reverse letter order is 'ge'.
'lie'+'ge'='LIEGE'
'somewhere' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for liege that I've seen before include "Faithful," , "Vassal; city in Belgium" , "Loyal subject" , "Belgian city or feudal chief" , "European province" .)
