Romantic queen in a low country (7)
I believe the answer is:
amorous
'romantic' is the definition.
(thesaurus)
'queen in a low country' is the wordplay.
'queen' becomes 'r' (r is abbreviation regina. e.g. in ER ).
'in' indicates putting letters inside.
'low' becomes 'moo' ('moo' can be a synonym of 'low').
'country' becomes 'us' (US is an example**).
'a'+'moo'='amoo'
'r' going inside 'amoo' is 'amoro'.
'amoro'+'us'='AMOROUS'
(Other definitions for amorous that I've seen before include "Expressing love" , "Relating to love" , "A US room used for loving" , "Feeling desire" , "In loving mood" .)
