Land is also ground (4)
I believe the answer is:
laos
'land' is the definition.
(Laos is an example)
'also ground' is the wordplay.
'ground' indicates anagramming the letters ('grind' the letters into a new form).
'also' anagrammed gives 'LAOS'.
'is' is the link.
(Other definitions for laos that I've seen before include "Mountainous state in southeastern Asia" , "South-east Asian republic, capital Vientiane" , "Country of Indo-China, capital Vientiane" , "Country between Thailand/Vietnam" , "Country of SE Asia" .)
