Give orders to person in charge (4)
I believe the answer is:
boss
I believe this clue is a triple definition!
'give orders to' is the first definition.
(I've seen this in another clue)
'person' is the second definition.
(boss is a kind of person)
'in charge' is the third definition.
(thesaurus)
(Other definitions for boss that I've seen before include "One in charge; stud" , "designer" , "Master - stud" , "Manager (colloq.); stud" , "Domineer" .)
