Loyalty programme? Form of realism I injected (3,5)
I believe the answer is:
air miles
'loyalty programme? form' is the definition.
I can't judge whether this defines the answer.
'of realism i injected' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'injected' means one lot of letters goes inside another (inserted letters are injected).
'realism' is an anagram of 'airmles'.
'airmles' enclosing 'i' is 'AIR MILES'.
Can you help me to learn more?
(Other definitions for air miles that I've seen before include "award for being high-flier?" , "Fliers' accumulated points" .)
