Obliged, we hear, to supply tabulated item (4)
I believe the answer is:
tide
'item' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tide that I've seen before include "(With time) it waits for no man" , "Ocean movement" , "Current, ebb" , "Periodic water movement" , "Powerful surge" .)
