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 a hidden word.
'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" .)
