A German trained as manager, for example (7)
I believe the answer is:
anagram
'example' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'a german trained as manager' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is found in the answer.
'german' could be 'g' (abbreviation) and 'g' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for anagram that I've seen before include "Word arranging the letters of another" , "Scramble of letters (to make trestle, perhaps)" , "Word that rearranges another's letters" , "Word rearranging another's letters" , "a mix of characters" .)
