Pass, slip, and fall down (8)
I believe the answer is:
collapse
'fall down' is the definition.
(thesaurus)
'pass slip' is the wordplay.
'pass' becomes 'col' (col is a kind of pass).
'slip' becomes 'lapse' (lapsing is a kind of slipping**).
'col'+'lapse'='COLLAPSE'
'and' is the link.
(Other definitions for collapse that I've seen before include "Slump" , "Founder" , "fold" , "Fall down or lose strength suddenly" , "Fall or disintergrate" .)
