Row with strapper (4)
I believe the answer is:
tier
This clue could be a double definition.
'row' is the first definition.
(a tier is a row of things)
'strapper' is the second definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
'with' acts as a link.
Can you help me to learn more?
(Other definitions for tier that I've seen before include "he hasn't won?" , "One making knot - level" , "this person secures" , "Level - layer" , "Echelon" .)
