Small sprite within (5)

I believe the answer is:

elfin

'small' is the definition.
(similar in meaning)

'sprite within' is the wordplay.
'sprite' becomes 'elf' (an elf is a sprite).
'within' becomes 'in'.
'elf'+'in'='ELFIN'

(Other definitions for elfin that I've seen before include "Petite and charming" , "Delicately framed" , "little character" , "Like a mischievous fairy" , "Fairy-like" .)

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