A flurry about Burmese title that's imposing (6)
I believe the answer is:
august
'imposing' is the definition.
(I've seen this before)
'a flurry about burmese title' is the wordplay.
'flurry' becomes 'gust' (I've seen this before).
'about' says to put letters next to each other.
'burmese title' becomes 'U' (as in U Thant, former UN Secretary General).
'gust' after 'u' is 'ugust'.
'a'+'ugust'='AUGUST'
'that's' is the link.
(Other definitions for august that I've seen before include "Month befitting a lord" , "a period for taking holidays?" , "Inspiring reverence" , ". . . . . . is a Wicked Month (Edna O'Brien)" , "part of the year" .)
