Inadequate to examine terms in theology (6)
I believe the answer is:
scanty
'inadequate' is the definition.
(I've seen this before)
'examine terms in theology' is the wordplay.
'examine' becomes 'scan' (scanning is a kind of examining).
'terms in theology' becomes 'ty' (I can't explain this - if you can you should give a lot more credence to this answer).
'scan'+'ty'='SCANTY'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for scanty that I've seen before include "Inadequate" , "Insufficient in quantity" , "(Of clothing) revealing" , "Of small amount, barely enough" , "Spare" .)
