A lot dumped by intolerant apprentice (6)
I believe the answer is:
intern
This clue could be a double definition.
'a lot' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'dumped by intolerant apprentice' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for intern that I've seen before include "Imprison without trial - hospital junior doctor" , "Deprive of freedom" , "Confine the hospital resident" , "Imprison (eg, alien) as a precautionary measure" , "House officer" .)
