Catch on a small branch (4)

I believe the answer is:

twig

I believe this clue is a double definition.

'catch on' is the first definition.
('twig' can be a synonym of 'catch on')

'a small branch' is the second definition.
(I've seen this before)

(Other definitions for twig that I've seen before include "Small woody shoot" , "Small tree shoot" , "Division of branch" , "Small shoot or branch" , "small piece in plane, say" .)

I've seen this clue in The Telegraph.
