Straight bit of river to arrive at (5)
I believe the answer is:
reach
This might be a double definition.
'straight bit of river' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'arrive at' is the second definition.
(synonyms)
'to' is the link.
Can you help me to learn more?
(Other definitions for reach that I've seen before include "Get in touch" , "Get to; extent" , "stretch of canal between locks" , "Open stretch of water" , "It's an advantage for a boxer" .)
