Studied: was inclined to receive element of basic education? (6)
I believe the answer is:
learnt
'studied' is the definition.
(I've seen this before)
'inclined to receive element of basic education?' is the wordplay.
'inclined' becomes 'leant' (I've seen this before).
'to receive' is an insertion indicator.
'element of basic education?' becomes 'R' (as in the three R's).
'leant' going around 'r' is 'LEARNT'.
'was' is the link.
(Other definitions for learnt that I've seen before include "Found out" , "Realised" , "Aquired knowledge or skill" , "Studied" , "Picked up" .)
