Land conservationists originally owned? (4)
I believe the answer is:
chad
'land' is the definition.
(Chad is an example)
'conservationists originally owned?' is the wordplay.
'originally' suggests taking the first letters.
'owned?' becomes 'had' ('have' can be a synonym of 'own').
The initial letter of 'conservationists' is 'c'.
'c'+'had'='CHAD'
(Other definitions for chad that I've seen before include "N.Central African Republic" , "Large, shallow lake in north central Africa" , "African country and lake" , "hanging has helped elect president?" , "Paper punch waste; African country" .)
