Visit sites on moor, as it were? That's too much (7)
I believe the answer is:
surfeit
This could be a double definition.
'visit sites on moor' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'it were? that's too much' is the second definition.
The definition suggests a singular noun which matches the answer.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for surfeit that I've seen before include "stuff, once" , "Superabundance" , "it's more than one needs" , "Overindulgence" , "having had quite enough" .)
