Accompany someone unleashing essentially offensive language (7)
I believe the answer is:
tagalog
'language' is the definition.
(Tagalog is an example)
'accompany someone unleashing essentially offensive' is the wordplay.
I cannot really see how this works, but
'someone' could be 'gal' (gal is a kind of someone) and 'gal' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tagalog that I've seen before include "Asian language" , "Pacific islander" , "people in the Philippines" .)
