Root' - name for a country (6)
I believe the answer is:
sweden
'for a country' is the definition.
(Sweden is an example)
'root' name' is the wordplay.
'root'' becomes 'swede' (I've seen this before).
'name' becomes 'n' (common abbreviation e.g. on forms).
'swede'+'n'='SWEDEN'
(Other definitions for sweden that I've seen before include "land" , "in E" , "We send out to here, oddly" , "Country with blue and yellow flag" , "ditto" .)
