Get a learner in a state of ire! (4)
I believe the answer is:
rile
'get' is the definition.
(I know that get is a more specific form of the action rile)
'a learner in a state of ire' is the wordplay.
'a learner' becomes 'l' (as in a learner driver with L-plates on their car).
'in' means one lot of letters goes inside another.
'a state' becomes 'RI' (Rhode Island abbreviation).
'of ire' becomes 'e' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ri'+'e'='rie'
'l' going within 'rie' is 'RILE'.
Can you help me to learn more?
(Other definitions for rile that I've seen before include "Bother" , "Get up nose of" , "Make angry" , "Irk" , "Lire (anag)" .)
