Get up when caught on object (6)
I believe the answer is:
ascend
'get up' is the definition.
'when caught on object' is the wordplay.
'when' becomes 'as'.
'caught' becomes 'c' (cricket abbreviation).
'on' says to put letters next to each other.
'object' becomes 'end' (I've seen this in other clues**).
'as'+'c'+'end'='ASCEND'
(Other definitions for ascend that I've seen before include "Take off" , "Get higher" , "Mount" , "Travel upwards" , "shift to a higher plane" .)
