Life, for example (6)
I believe the answer is:
cereal
'life for example' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cereal that I've seen before include "Food prepared from grain" , "Breakfast dish" , "Rye, for example" , "Grass producing an edible grain" , "Common part of breakfast" .)
