And what have you from Rome? (2,6)
I believe the answer is:
et cetera
'rome?' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I don't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for et cetera that I've seen before include "That can reduce length of sentence" , "Drive out, expel" , "And the rest (Latin)" , "that reduces length of sentence" , "'And so forth (2,6)'" .)
