A schoolboy howler? (7)
I believe the answer is:
crybaby
This clue might be a double definition.
'a schoolboy' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'howler?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
Can you help me to learn more?
(Other definitions for crybaby that I've seen before include "Person too easily reduced to tears" , "One shedding tears frequently" , "Person often shedding tears" , "One who weeps easily without good cause" , "One sheds tears easily" .)
