Everyone up in woodland to give way (8)
I believe the answer is:
collapse
'give way' is the definition.
(synonyms)
'everyone up in woodland' is the wordplay.
'everyone' becomes 'all' (all people).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'in' means one lot of letters goes inside another.
'woodland' becomes 'copse' (I can't justify this - if you can you should believe this answer much more).
'all' in reverse letter order is 'lla'.
'lla' going inside 'copse' is 'COLLAPSE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for collapse that I've seen before include "Crumble" , "Break-down or complete failure" , "Fall down unconscious" , "Disintegration" , "Faint and fall" .)
