Lined up while involved in a disagreement? (2,1,3)
I believe the answer is:
in a row
'lined up' is the definition.
(I've seen this in another clue)
'in a disagreement?' is the wordplay.
'disagreement?' becomes 'row' (row is a kind of disagreement).
'in'+'a'+'row'='IN A ROW'
'while involved' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for in a row that I've seen before include "Lined up" , "becoming involved in disturbance" , "One after another" , "running" , "Consecutively" .)
