To become ecstatic without delay is out of the way! (5)
I believe the answer is:
swoon
'to become ecstatic' is the definition.
I can't tell whether this defines the answer.
'without delay is out of the way' is the wordplay.
'without delay' becomes 'soon'.
'is out of' is an insertion indicator (some letters on the outside of others).
'the way' becomes 'w' (Compass direction - West).
'soon' going around 'w' is 'SWOON'.
Can you help me to learn more?
(Other definitions for swoon that I've seen before include "Fall fainting" , "Show ecstasy" , "Display of extreme emotion" , "Lose consciousness" , "Faint (with emotion)" .)
