It followed alongside us negotiating partial rise (6)
I believe the answer is:
ensued
'it followed' is the definition.
The definition suggests a singular noun but the answer is not.
'alongside us negotiating partial rise' is the wordplay.
'partial' indicates a hidden word.
'rise' is a reversal indicator.
'deusne' is hidden in the letters of 'alongside us negotiating'.
'deusne' reversed gives 'ENSUED'.
Can you help me to learn more?
(Other definitions for ensued that I've seen before include "Occurred afterwards" , "Happened afterwards or as a result" , "Romantic rendezvous" , "Came about as consequence" , "Resulted, followed" .)
