Asian language quiz’s break over intervals (5)

I believe the answer is:

uzbek

I'm a little stuck... Click here to teach me more about this clue!

'asian language' is the definition.
(I've seen this in another clue)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for uzbek that I've seen before include "Coming from Tashkent" , "Someone from Tashkent?" , "Native of Tashkent, perhaps" , "Asian" , "Eg, native of Tashkent" .)

I've seen this clue in the Sydney Morning Herald.
