Some okapi eating crusty meal (3)
I believe the answer is:
pie
'meal' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'some okapi eating crusty' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'PIE' is hidden within 'okapi eating crusty'.
Can you help me to learn more?
(Other definitions for pie that I've seen before include "something with custard, say" , "Dish baked in pastry-lined pan" , "Bird - dish - mixed type" , "Small, former coin of India" , "what to cook for dinner?" .)
