Standard minor majorette carries (4)
I believe the answer is:
norm
'standard' is the definition.
(norm is a kind of standard)
'minor majorette carries' is the wordplay.
'carries' indicates the answer is hidden within the clue.
'NORM' is hidden within 'minor majorette'.
(Other definitions for norm that I've seen before include "(The) accepted way" , "Benchmark" , "Typical pattern or situation" , "Standard amount or customary behaviour" , "Expected standard" .)
