Appreciate serial rescheduled close to lunchtime (7)
I believe the answer is:
realise
'appreciate' is the definition.
(I know that appreciate is a more specific form of the action realise)
'serial rescheduled close to lunchtime' is the wordplay.
'rescheduled' is an anagram indicator (I've seen 'rescheduling' mean this (I've seen this in other clues)).
'close to' means one lot of letters go next to another.
'lunchtime' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'serial' is an anagram of 'realis'.
'realis'+'e'='REALISE'
Can you help me to learn more?
(Other definitions for realise that I've seen before include "Make concrete" , "Become aware of as a fact" , "Bring to fruition" , "Come to know" , "Understand - cash in" .)
