Keen to get around old dodge (5)
I believe the answer is:
avoid
'dodge' is the definition.
(I've seen this before)
'keen to get around old' is the wordplay.
'keen' becomes 'avid' (I've seen this before).
'to get around' indicates putting letters inside.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'avid' going around 'o' is 'AVOID'.
(Other definitions for avoid that I've seen before include "Run away from" , "Get out of" , "Bypass" , "Stay away from or circumvent" , "Steer clear of, dodge" .)
