Row the better half and I got into (4)
I believe the answer is:
tier
'row' is the definition.
(a tier is a row of things)
'the better half and i got into' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'better half' becomes 'er' (I can't justify this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'got into' means one lot of letters goes inside another.
't'+'er'='ter'
'ter' going around 'i' is 'TIER'.
Can you help me to learn more?
(Other definitions for tier that I've seen before include "Wedding cake layer" , "One who secures" , "One of two or more rows" , "One making knot - level" , "Rank - row" .)
