East African runner maintaining small store on a farm (6)
I believe the answer is:
ensile
'store on a farm' is the definition.
(I've seen this in another clue)
'east african runner maintaining small' is the wordplay.
'east' becomes 'e' (abbreviation).
'african runner' becomes 'nile' (Nile River is an example. I am not sure about the 'african' bit.).
'maintaining' is an insertion indicator (inserted letters are held or maintained).
'small' becomes 's' (abbreviation - e.g. clothes size).
'nile' placed around 's' is 'nsile'.
'e'+'nsile'='ENSILE'
Can you help me to learn more?
(Another definition for ensile that I've seen is " Store green fodder in pits, etc.".)
