Continuously move up bound by rope? (8)
I believe the answer is:
together
'continuously' is the definition.
(thesaurus)
'move up bound by rope?' is the wordplay.
'move' becomes 'go' (to go is to move).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'bound by' means one lot of letters goes inside another (inserted letters are held or bound).
'rope?' becomes 'tether' (I've seen this in another clue).
'go' written backwards gives 'og'.
'og' inserted inside 'tether' is 'TOGETHER'.
(Other definitions for together that I've seen before include "In each other's company" , "Not apart" , "Well-balanced" , "in concert" , "tied" .)
