Medic spread oil on Indian radish (5)
I believe the answer is:
mooli
'indian radish' is the definition.
'mooli' can be an answer for 'radish' (I've seen this before). I'm not certain of the 'indian' bit.
'medic spread oil on' is the wordplay.
'medic' becomes 'mo' (medical officer).
'spread' indicates an anagram.
'on' indicates putting letters inside (as in clothing \'on\' a person).
'oil' is an anagram of 'oli'.
'mo' going inside 'oli' is 'MOOLI'.
Can you help me to learn more?
(Other definitions for mooli that I've seen before include "root vegetable" , "Large white radish" , "Radish-like root" .)
