Professional jargon in string of muddling orders (5)
I believe the answer is:
lingo
'professional jargon' is the definition.
'lingo' can be an answer for 'jargon' (synonyms). I am unsure of the 'professional' bit.
'string of muddling orders' is the wordplay.
'string of' indicates a hidden word (a string of letters from the clue).
'LINGO' can be found hidden inside 'muddling orders'.
'in' is the link.
Can you help me to learn more?
(Other definitions for lingo that I've seen before include "Log in (anag.)" , "Argot" , "means to communicate" , "strange language" , "Johnny Foreigner speaks one" .)
