Deciding where one is drawing the line? (6)
I believe the answer is:
ruling
'deciding' is the definition.
(ruling is a kind of deciding)
'one is drawing the line?' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'line?' could be 'l' (used when specifying particular lines from a poem) and 'l' is found in the answer.
The remaining letters 'rung' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'where' acts as a link.
Can you help me to learn more?
(Other definitions for ruling that I've seen before include "Court decision" , "Drawing a fine line" , "Decree" , "judgment" , "currently in force" .)
