Sherpa disconcerted by so many words (6)
I believe the answer is:
phrase
'so many words' is the definition.
'phrase' can be an answer for 'words' (I have seen 'The words' mean 'phrase' so perhaps 'words' could also mean 'phrase'). I'm unsure of the 'so many' bit.
'sherpa disconcerted' is the wordplay.
'disconcerted' indicates anagramming the letters.
'sherpa' with letters rearranged gives 'PHRASE'.
'by' is the link.
Can you help me to learn more?
(Other definitions for phrase that I've seen before include "partial sentence" , "a certain expression" , "Express in words" , "Expression without a verb" , "Short, coherent group of words" .)
