Wild rush almost made an impression (7)
I believe the answer is:
stamped
'made an impression' is the definition.
(I've seen this before)
'wild rush almost' is the wordplay.
'wild rush' becomes 'stampede' (I've seen this before).
'almost' means to remove the last letter (almost the whole word is kept).
'stampede' with its last letter taken off is 'STAMPED'.
(Other definitions for stamped that I've seen before include "made an impression" , "Brought the foot down loudly" , "trampled" , "Impressed" , "Walked noisily or angrily" .)
