Country worker penning love lines (7)
I believe the answer is:
holland
'country' is the definition.
(Holland is an example)
'worker penning love lines' is the wordplay.
'worker' becomes 'hand' (hand is a kind of worker).
'penning' indicates putting letters inside.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'lines' becomes 'll' (I've seen this in other clues**).
'o'+'ll'='oll'
'hand' placed around 'oll' is 'HOLLAND'.
(Other definitions for holland that I've seen before include "European country" , "European kingdom" , "Don Hall is in the Netherlands" .)
