Asian giant to be included (7)
I believe the answer is:
tibetan
'asian' is the definition.
(I know that Tibetan is a type of asian)
'giant to be included' is the wordplay.
'giant' becomes 'titan' (synonyms).
'included' means one lot of letters goes inside another.
'titan' placed around 'be' is 'TIBETAN'.
(Other definitions for tibetan that I've seen before include "Oriental" , "Nationality of citizen of Lhasa, before Chinese invasion" , "Nationality of the Dalai Lama" , "native of Lhasa, say?" , "Language giving us yak, sherpa and yeti" .)
