Crossword Genius

Kept being uncommunicative (8)

Ross

I believe the answer is:

reserved

I believe this is a double definition.

'kept' is the first definition.
(to keep is to reserve or hold onto)

'uncommunicative' is the second definition.
(thesaurus)

'being' acts as a link.

(Other definitions for reserved that I've seen before include "Slow to show emotions" , "Uncommunicative, not extrovert" , "without emotion" , "Reticent; put by" , "Kept back" .)

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