Cave in woody area: everyone enters the wrong way (8)
I believe the answer is:
collapse
'cave in' is the definition.
(synonyms)
'woody area everyone enters the wrong way' is the wordplay.
I cannot really understand how this works, but
'area' could be 'apse' (I have seen 'Area of church ' mean 'apse' so perhaps 'area' could also mean 'apse') and 'apse' is present in the answer.
The remaining letters 'coll' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for collapse that I've seen before include "Fall down or lose strength suddenly" , "Fall down unconscious" , "Slump" , "Fall down suddenly like escallop" , "Fall down, building or business" .)
