Shows, signals (9)
I believe the answer is:
indicates
This clue is a double definition.
'shows' is the first definition.
('indicate' can be a synonym of 'show')
'signals' is the second definition.
('indicate' can be a synonym of 'signal')
(Other definitions for indicates that I've seen before include "Signals or points to" , "Shows, signals" , "Signals, suggests" .)
