Jump onto coach after morning with husband (6)
I believe the answer is:
ambush
'jump onto' is the definition.
(ambush can mean to jump onto and attack)
'coach after morning with husband' is the wordplay.
'coach' becomes 'bus' (synonyms).
'after' means one lot of letters go next to another.
'morning' becomes 'am'.
'with' is a charade indicator (letters next to each other).
'husband' becomes 'h'.
'bus' put after 'am' is 'ambus'.
'ambus'+'h'='AMBUSH'
(Other definitions for ambush that I've seen before include "Lying in wait to attack" , "Await and intercept unexpectedly" , "spring a trap" , "Scene of lying in wait" , "Launch attack from hiding" .)
