Nerds perhaps giving evening courses (7)
I believe the answer is:
dinners
This could be a double definition.
'nerds' is the first definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.
'giving evening courses' is the second definition.
The definition and answer can be both things that one consumes for nourishment as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for dinners that I've seen before include "Evening meals" , "celebratory events" , "Main meals" , "Formal meals" .)
