Can be found in deli speaking to dishy type (6)
I believe the answer is:
indian
'dishy type' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'can be found in deli speaking' is the wordplay.
I cannot quite see how this works, but
'in' is within the answer.
The remaining letters 'dian' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for indian that I've seen before include "IDA inn provided for this notionality" , "Native American or denizen of New Delhi, say" , "Eg, native of Delhi" , "May be Asiatic or N. American" , "This summer may happen in late autumn" .)
