Celebration with US author, originator of young American children’s heroine (7)
I believe the answer is:
dorothy
'american children's heroine' is the definition.
I can't judge whether this defines the answer.
'celebration with us author originator of young' is the wordplay.
'celebration' becomes 'do' (I've seen this in other clues).
'with' says to put letters next to each other.
'us author' becomes 'Roth' (novelist Philip Roth).
'originator of' says to take the initial letters (I've seen 'originator' mean this).
The first letter of 'young' is 'y'.
'do'+'roth'+'y'='DOROTHY'
Can you help me to learn more?
(Other definitions for dorothy that I've seen before include "Woman" , "Female" , "Wizard of Oz child" , "Girl from Kansas" , "Name of the young heroine in 'The Wizard of Oz'" .)
