Row with the better half and I intervene (4)
I believe the answer is:
tier
'row' is the definition.
(a tier is a row of things)
'better half and i intervene' is the wordplay.
I cannot really see how this works, but
'i' is within the answer.
'better half' could be 'ter' and 'ter' is found within the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'with the' acts as a link.
Can you help me to learn more?
(Other definitions for tier that I've seen before include "Rank - row" , "Plague" , "Row, level" , "Layer, rank" , "One securing" .)
