Row as result of clock losing minutes? (4)
I believe the answer is:
tier
'row' is the definition.
(a tier is a row of things)
'clock losing minutes?' is the wordplay.
'clock' becomes 'timer' (something which times).
'losing' indicates named letters should be taken away.
'minutes?' becomes 'm' (common abbreviation).
'timer' with 'm' taken away is 'TIER'.
'as result of' is the link.
(Other definitions for tier that I've seen before include "One making knot - level" , "Rite (anag.)" , "this person secures" , "Row - one forming a knot" , "Person joining" .)
