Language so wantonly awful hussar is left incensed at front (7)

I believe the answer is:

swahili

'language' is the definition.
(Swahili is an example)

'so wantonly awful hussar is left incensed at front' is the wordplay.
'at front' indicates taking the first letters.
The first letters of 'so wantonly awful hussar is left incensed' is 'SWAHILI'.

(Other definitions for swahili that I've seen before include "Language widely used in East Africa" , "E. African language" , "East African language" , "Common language of E. Africa" , "African people" .)

I've seen this clue in The Independent.
