Unsettle routine activities in attempt to rise (7)
I believe the answer is:
disturb
'unsettle' is the definition.
(I've seen this in another clue)
'routine activities in attempt to rise' is the wordplay.
'routine activities' becomes 'ruts' (rut is a kind of activity. I am not sure about the 'routine' bit.).
'in' indicates putting letters inside.
'attempt' becomes 'bid' (bid is a kind of attempt).
'to rise' says the letters should be written in reverse.
'ruts' inserted inside 'bid' is 'brutsid'.
'brutsid' backwards is 'DISTURB'.
Can you help me to learn more?
(Other definitions for disturb that I've seen before include "Upset - agitate" , "Agitate - ruffle - trouble" , "Interrupt, annoy" , "Break" , "Interrupt; upset" .)
