More willing to pass over and back out? (7)
I believe the answer is:
readier
'more willing' is the definition.
('ready' is associated in meaning with 'willing')
'pass over and back out?' is the wordplay.
'pass over' becomes 'dier' (I can't justify this - if you can you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'back' becomes 'rear' (something's rear is its back).
'out?' means to remove the last letter (I've seen 'out' mean this).
'rear' with its final letter removed is 'rea'.
'dier' after 'rea' is 'READIER'.
'to' is the link.
Can you help me to learn more?
(Other definitions for readier that I've seen before include "more immediately available" , "More willing" , "More prepared" .)
