Tashkent native and Zulu to remain in Great Britain? (5)
I believe the answer is:
uzbek
'tashkent native' is the definition.
(I've seen this in another clue)
'zulu to remain in great britain?' is the wordplay.
'zulu' becomes 'Z' (phonetic alphabet: alpha, bravo, charlie etc.).
'to remain' becomes 'be' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'great britain?' becomes 'UK' (synonyms).
'z'+'be'='zbe'
'zbe' going inside 'uk' is 'UZBEK'.
'and' acts as a link.
(Other definitions for uzbek that I've seen before include "Native of Tashkent, perhaps" , "Asian" , "Eg, native of Tashkent" , "Someone from Tashkent?" , "Language of Tashkent" .)
