Colonel slipped then fell over (9)
I believe the answer is:
collapsed
'fell over' is the definition.
'collapsed' can be an answer for 'fell' (I've seen this before). I am not sure about the 'over' bit.
'colonel slipped' is the wordplay.
'colonel' becomes 'col'.
'slipped' becomes 'lapsed' (lapsing is a kind of slipping).
'col'+'lapsed'='COLLAPSED'
'then' acts as a link.
Can you help me to learn more?
(Other definitions for collapsed that I've seen before include "Cracked up - gave way" , "laid low" , "Fell apart" , "Gave way, caved in" .)
