Young people cry when lifted up over your head (4)
I believe the answer is:
boys
'young people' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
'cry when lifted up over your head' is the wordplay.
'cry when' becomes 'sob' (sobbing is a kind of crying. I am not sure about the 'when' bit.).
'lifted up' says the letters should be written in reverse (in a down clue, letters go up).
'over' is an insertion indicator.
'head' indicates taking the first letters.
The first letter of 'your' is 'y'.
'sob' back-to-front is 'bos'.
'bos' enclosing 'y' is 'BOYS'.
Can you help me to learn more?
(Other definitions for boys that I've seen before include "Beach --, group" , "Male children" , "They will be themselves, it's said" , "Lads" , "Young males" .)
