Some European or habitually negligent Scot? (9)
I believe the answer is:
slovenian
'some european' is the definition.
(Slovenian is an example)
'habitually negligent scot?' is the wordplay.
'habitually negligent' becomes 'sloven' (a sloven is an untidy or careless person).
'scot?' becomes 'ian' (Scottish given name).
'sloven'+'ian'='SLOVENIAN'
'or' acts as a link.
(Other definitions for slovenian that I've seen before include "Eg, native of Ljubljana" , "Central European" , "From a European country" .)
