Referred deal, subject to review involving Law Lord (7)
I believe the answer is:
alluded
'referred' is the definition.
(I've seen this before)
'deal subject to review involving law lord' is the wordplay.
'deal subject' becomes 'dela' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to review' says the letters should be written backwards.
'involving' means one lot of letters goes inside another.
'law lord' becomes 'lud' (term used in law as in m'lud, my lord).
'dela' in reverse letter order is 'aled'.
'aled' enclosing 'lud' is 'ALLUDED'.
Can you help me to learn more?
(Other definitions for alluded that I've seen before include "Hinted (at)" , "Referred" , "Mentioned in passing" , "Adverted" , "Pereferred briefly or indirectly to in speaking" .)
