Highest point arrived with Charlie in second place (4)
I believe the answer is:
acme
'highest point' is the definition.
(I've seen this in another clue)
'arrived with charlie in second place' is the wordplay.
I cannot quite understand how this works, but
'charlie' could be 'c' (phonetic alphabet: alpha, bravo, charlie etc.) and 'c' is found within the answer.
The remaining letters 'ame' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for acme that I've seen before include "Point of maximum development" , "Zenith - optimum" , "Summit of achievement" , "Top or highest point" , "Came awkwardly to the highest point" .)
