Rope going up without delay on execution’s beginning? (5)
I believe the answer is:
noose
'rope' is the definition.
(noose is a kind of rope)
'going up without delay on execution's beginning?' is the wordplay.
'going up' says the letters should be written in reverse.
'without delay' becomes 'soon'.
'on' says to put letters next to each other.
'beginning?' indicates taking the first letters (I've seen 'beginnings' mean this).
The first letter of 'executions' is 'e'.
'soon' backwards is 'noos'.
'noos'+'e'='NOOSE'
(Other definitions for noose that I've seen before include "Loop with running knot" , "Hangman's equipment" , "Hangman's or cowboy's loop" , "Catcher" , "Snare, restraint" .)
