Single out character sometimes dropped in language (7)
I believe the answer is:
english
'language' is the definition.
(English language is an example)
'single out character' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'character' becomes 'h' (**).
'single' with letters rearranged gives 'englis'.
'englis'+'h'='ENGLISH'
'sometimes dropped in' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for english that I've seen before include "Common language" , "- rose; - breakfast" , "See 10" , "Widely-spoken language" , "The Queen's language?" .)
