Feature some extra items (5)

I believe the answer is:

trait

'feature' is the definition.
(I've seen this before)

'some extra items' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'TRAIT' is hidden within 'extra items'.

(Other definitions for trait that I've seen before include "Distinguishing characteristic of personality" , "A characteristic of straitened kind" , "Attribute, characteristic" , "Idiosyncrasy" , "Habit" .)

I've seen this clue in The Telegraph.
