Charlie more than 400m behind given a hand (7)
I believe the answer is:
clapped
'charlie more than 400m' is the definition.
I can't judge whether this definition defines the answer.
'behind given a hand' is the wordplay.
'behind' becomes 'ped' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'given' is a charade indicator (letters next to each other).
'a hand' becomes 'clap' (both can mean a round of applause).
'ped' after 'clap' is 'CLAPPED'.
Can you help me to learn more?
(Other definitions for clapped that I've seen before include "Applauded" , "Acclaimed" .)
