Pondered, contemplated (5)
I believe the answer is:
mused
I believe this clue is a double definition.
'pondered' is the first definition.
('muse' can be a synonym of 'ponder')
'contemplated' is the second definition.
('muse' can be a synonym of 'contemplate')
(Other definitions for mused that I've seen before include "Was deep in thought" , "Was absorbed in thought" , "Closer" , "'Meditated, mulled (5)'" , "Fuddled" .)
