Language of some yelling obscenities (5)
I believe the answer is:
lingo
'language' is the definition.
(lingo is a kind of language)
'some yelling obscenities' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'LINGO' can be found hidden inside 'yelling obscenities'.
'of' is the link.
(Other definitions for lingo that I've seen before include "Foreign language or dialect: jargon" , "Specialised vocabulary" , "Jargon, language (colloq.)" , "speech" , "Jargon, foreign language (informal)" .)
