Name of man in some short form (5)
I believe the answer is:
simon
'name of man' is the definition.
'Simon' can be an answer for 'man' (I've seen this before). I am not sure about the 'name of' bit.
'in some short form' is the wordplay.
'short' means to remove the last letter.
'form' indicates anagramming the letters (another form of the letters).
'in'+'some'='insome'
'insome' with its final letter taken off is 'insom'.
'insom' anagrammed gives 'SIMON'.
Can you help me to learn more?
(Other definitions for simon that I've seen before include "he says it's a game" , "Bolivar, de Montfort, Callow or Cowell?" , "He's simple in rhyme" , "- Templar, The Saint" , "- Bol'var, S. American liberator" .)
