Kind of speech I had given shortly after power drink (6)
I believe the answer is:
pidgin
'kind of speech' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'i had given shortly after power drink' is the wordplay.
'i had' becomes 'I'd' (contraction).
'given' is a charade indicator (letters next to each other).
'shortly after' becomes 'gin' (I can't justify this - if you can you should believe this answer much more).
'power' becomes 'p' (symbol in physics).
'drink' means one lot of letters goes inside another.
'gin' put after 'p' is 'pgin'.
'id' placed within 'pgin' is 'PIDGIN'.
Can you help me to learn more?
(Other definitions for pidgin that I've seen before include "Language mix" , "Simple form of mixed language" , "form of communication" , "Two-language mix" , "Simplified (English) language" .)
