Indecent, having name for sergeant major's barking (5)
I believe the answer is:
nutty
'indecent' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'name for sergeant major's barking' is the wordplay.
I cannot quite understand how this works, but
'name' could be 'ty' and 'ty' is present in the answer.
The remaining letters 'nut' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'having' is the link.
Can you help me to learn more?
(Other definitions for nutty that I've seen before include "Crazy -- tasting of almonds" , "Mad (colloq.)" , "passionate" , "Insane" , "Bonkers - containing almonds etc" .)
