Lawyer oddly lacking in Scottish town (3)
I believe the answer is:
ayr
'scottish town' is the definition.
(I've seen this before)
'lawyer oddly lacking' is the wordplay.
'oddly lacking' means one should take alternating letters.
The alternating letters of 'lawyer' are 'AYR'.
'in' acts as a link.
(Other definitions for ayr that I've seen before include "Scots. town; sounds like song" , "Race course" , "Scottish town, port and racecourse" , "Scottish town sounds tuneful" , "Scottish salmon river" .)
