Shingle broken up for old printing type (7)
I believe the answer is:
english
'old printing type' is the definition.
(as in Old English)
'shingle broken up' is the wordplay.
'broken up' indicates an anagram.
'shingle' anagrammed gives 'ENGLISH'.
'for' is the link.
(Other definitions for english that I've seen before include "Language spoken in his glen, strangely" , "The . . . . . . . Patient (film) (7)" , "International language, by assumption" , "speech" , "A country condiment?" .)
