Look for regular meeting-place, missing area (4)
I believe the answer is:
hunt
'look for' is the definition.
(to hunt for something is to look for it)
'regular meeting-place missing area' is the wordplay.
'regular meeting place' becomes 'haunt' (haunt can mean a place that people visit regularly).
'missing' indicates named letters should be taken away.
'area' becomes 'a' (maths abbreviation).
'haunt' with 'a' removed is 'HUNT'.
(Other definitions for hunt that I've seen before include "Forage" , "Meet - famous mountaineer" , "Search (with dogs?)" , "Pursue game" , "Search; chase" .)
