Group of words comes apart in speech (6)
I believe the answer is:
phrase
This might be a double definition.
'group of words' is the first definition.
(I've seen this before)
'apart in speech' is the second definition.
'phrase' can be an answer for 'speech' (phrase is a kind of speech). I am not sure about the 'apart in' bit.
'comes' is the link.
Can you help me to learn more?
(Other definitions for phrase that I've seen before include "Express in words" , "Short expression" , "partial sentence" , "Put into words" , "Present" .)
