In Arapaho, an exclamation of disgust (3)

I believe the answer is:

pah

'exclamation of disgust' is the definition.
(I've seen this in another clue)

'in arapaho an' is the wordplay.
'in' indicates a hidden word.
'PAH' can be found hidden inside 'arapaho an'.

(Another definition for pah that I've seen is " Expression of disgust".)

I've seen this clue in the Evening Standard.
