Language in queer sentence (4)

I believe the answer is:

erse

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

'in queer sentence' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ERSE' is hidden in the letters of 'queer sentence'.

(Other definitions for erse that I've seen before include "Old Scots or Irish Gaelic" , "Old Celtic language" , "Irish Gaelic language" , "Possibly the language" , "Celtic tongue" .)

I've seen this clue in The Mirror.
