Follow example, keeping husband (5)
I believe the answer is:
chase
'follow' is the definition.
(I know that chase is a more specific form of the action follow)
'example keeping husband' is the wordplay.
'example' becomes 'case' (case can mean an example or instance of something).
'keeping' means one lot of letters goes inside another.
'husband' becomes 'h'.
'case' going around 'h' is 'CHASE'.
(Other definitions for chase that I've seen before include "Hurry" , "Engrave - hunt - pursue" , "Pursue; decorate (metal) by engraving" , "grave, as before?" , "trail" .)
