Maid told fib, essentially, suggesting this can be used as a dip (5)
I believe the answer is:
aioli
This might be a double definition.
'maid told fib essentially suggesting this can' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'a dip' is the second definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'be used as' acts as a link.
Can you help me to learn more?
(Other definitions for aioli that I've seen before include "garlic sauce" , "Garlic-flavoured mayonnaise" , "Garlicky mayonnaise" , "Mayonnaise with garlic" , "Mayo, in part?" .)
