Demosthenes had more than the rest (4)
I believe the answer is:
most
'more than the rest' is the definition.
I can't judge whether this defines the answer.
'demosthenes had' is the wordplay.
'had' says the answer is hidden in the clue (I've seen 'having' mean this).
'MOST' is hidden within 'demosthenes'.
Can you help me to learn more?
(Other definitions for most that I've seen before include "In the highest degree" , "Extremely, very" , "Nearly all, majority" , "Almost all" , "Greatest in amount or degree" .)
