Junior school? (3)
I believe the answer is:
fry
This clue could be a double definition.
'junior' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'school?' is the second definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for fry that I've seen before include "Young fish, especially when newly hatched" , "Christopher" , "Small fish for the pan" , "Cook small fish this way" , "Quaker Elizabeth's" .)
