Aileen rattled another woman (6)

I believe the answer is:

elaine

I'm a little stuck... Click here to teach me more about this clue!

'another woman' is the definition.
'Elaine' can be an answer for 'woman'. I'm not sure about the 'another' bit.

'aileen rattled' is the wordplay.
'rattled' is an anagram indicator.
'aileen' is an anagram of 'ELAINE'.

Can you help me to learn more?

(Other definitions for elaine that I've seen before include "Girl" , "-- Paige, singer" , ""The lily maid of Astolat"" , "Name" , "-- Paige, singer/actress" .)

I've seen this clue in The Telegraph.
