Idiot Scotsman biting your tongue? (8)
I believe the answer is:
assyrian
'tongue?' is the definition.
(Assyrian is an example)
'idiot scotsman biting your' is the wordplay.
'idiot' becomes 'ass' (I've seen this before**).
'scotsman' becomes 'ian'.
'biting' indicates putting letters inside (I've seen this in other clues).
'your' becomes 'yr'.
'ass'+'ian'='assian'
'assian' enclosing 'yr' is 'ASSYRIAN'.
(Other definitions for assyrian that I've seen before include "race" , "Extinct language" , "Old middle eastern type" , "ancient language" , "The - came down like the wolf on the fold (Byron)" .)
