Speaking or starting into a translation (7)
I believe the answer is:
oration
'speaking' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'or starting into a translation' is the wordplay.
'starting' becomes 'a' (I can't explain this - if you can you should give a lot more credence to this answer).
'a translation' is an anagram indicator.
'into' is an anagram of 'tion'.
'or'+'a'+'tion'='ORATION'
Can you help me to learn more?
(Other definitions for oration that I've seen before include "A formal or ceremonial speech" , "Platform speech" , "Major speech" , "Making a speech" , "Power of speech" .)
