Disregard for every command (7)
I believe the answer is:
skipper
'command' is the definition.
(thesaurus)
'disregard for every' is the wordplay.
'disregard' becomes 'skip' (I've seen this in another clue).
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'skip'+'per'='SKIPPER'
(Other definitions for skipper that I've seen before include "Senior pilot" , "who makes short hops" , "One who misses" , "delicate winger?" , "Head" .)
