Huge son going to the end, amusing people (6)
I believe the answer is:
comics
'amusing people' is the definition.
'comics' can be an answer for 'people' (comic is a kind of person). I'm unsure of the 'amusing' bit.
'huge son going to the end' is the wordplay.
'huge' becomes 'cosmic' (on a cosmic scale).
'son' becomes 's' (genealogical abbreviation for son).
'going' suggests deleting specific letters.
'to the end' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'cosmic' with 's' taken out is 'comic'.
'comic'+'s'='COMICS'
Can you help me to learn more?
(Other definitions for comics that I've seen before include "Entertainers" , "Funny performers" , "Funny men on stage" , "Funny people - may be stand-up" , "Cartoon periodicals" .)
