Little point accommodating learner — an idiot (4)
I believe the answer is:
dolt
'an idiot' is the definition.
(I know that idiot can be written as dolt)
'little point accommodating learner' is the wordplay.
'little point' becomes 'dot' (synonyms. I am not sure about the 'little' bit.).
'accommodating' means one lot of letters goes inside another.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'dot' enclosing 'l' is 'DOLT'.
Can you help me to learn more?
(Other definitions for dolt that I've seen before include "Slow-witted person" , "Fool" , "dope" , "Dullard" , "Dunce" .)
