Vegetarianism at last! Diet -- like this? (8)
I believe the answer is:
meatless
'last diet like this?' is the definition.
The definition suggests a singular noun but the answer is not.
'vegetarianism at' is the wordplay.
I cannot quite see how this works, but
'at' is within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for meatless that I've seen before include "Vegetarian" , "like Friday, perhaps" , "wanting some beef?" .)
