Had a feeling about (6)
I believe the answer is:
sensed
'had a feeling about' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sensed that I've seen before include "'Felt, perceived (6)'" , "Became aware through mental perception or intuition" , "Became vaguely aware of (something)" , "Felt, had mental impression" , "Felt, tasted, etc" .)
