Otto cunningly gets round mum for something to eat (6)
I believe the answer is:
tomato
'something to eat' is the definition.
(tomato is a kind of food)
'otto cunningly gets round mum' is the wordplay.
'cunningly' indicates an anagram.
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'round mum' becomes 'ma' (synonyms. I am not sure about the 'round' bit.).
'otto' with letters rearranged gives 'toto'.
'toto' going around 'ma' is 'TOMATO'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tomato that I've seen before include "Fruit used in salads" , "A motto, oddly, for this fruit" , "A motto, strangely, for this fruit" , "Salad fruit or berry" , "It's also known as a love apple" .)
