Journal of a father and a childless person (5)
I believe the answer is:
paper
'journal' is the definition.
(I've seen this before)
'a father and a childless person' is the wordplay.
'a father' becomes 'pa' (pa can mean dad or father).
'and' says to put letters next to each other.
'a childless person' becomes 'per' (I've seen this in other clues. I am not sure about the 'childless' bit.).
'pa'+'per'='PAPER'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for paper that I've seen before include "Journal" , "Short essay" , "conference presentation" , "Material made from wood pulp, say" , "Thin material used for writing, wrapping etc" .)
