Allude to a palindrome (5)

I believe the answer is:

refer

I believe this is a double definition.

'allude' is the first definition.
(I've seen this in another clue)

'palindrome' is the second definition.

'to a' acts as a link.

(Other definitions for refer that I've seen before include "Mention, cite" , "Advert, cite" , "Freer (anag.)" , "Advert, mention" , "Turn to (for information, authorisation etc)" .)

I've seen this clue in The Irish Independent and The Globe and Mail.
