Chase round area as ghosts do (5)
I believe the answer is:
haunt
'as ghosts do' is the definition.
(ghosts haunt people)
'chase round area' is the wordplay.
'chase' becomes 'hunt' (hunting is a kind of chasing).
'round' means one lot of letters goes inside another.
'area' becomes 'a' (maths abbreviation).
'hunt' placed around 'a' is 'HAUNT'.
(Other definitions for haunt that I've seen before include "place regularly visited" , "Visit in spectral form" , "Regular stamping ground" , "Place one frequents" , "Regularly visit" .)
