Over the turbulent river, note, you'll get somewhere (6)
I believe the answer is:
arrive
'get somewhere' is the definition.
'arrive' can be an answer for 'get' (synonyms). I'm unsure of the 'somewhere' bit.
'over the turbulent river note you'll' is the wordplay.
I cannot really understand how this works, but
an anagram of 'river' is 'rrive' which is within the answer.
'note' could be 'a' (musical note) and 'a' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for arrive that I've seen before include "To gain recognition" , "Make it" , "Show up" , "Reach goal" , "emerge" .)
