I felt ultimately satisfied (3)
I believe the answer is:
met
'satisfied' is the definition.
(as in 'met the conditions of his contract')
'i felt ultimately' is the wordplay.
'i' becomes 'me'.
'ultimately' indicates one should take the final letters.
The final letter of 'felt' is 't'.
'me'+'t'='MET'
(Other definitions for met that I've seen before include "Encountered by chance or arrangement" , "Encountered, came across" , "Made a connection" , "Opera company" , "Encountered or touched" .)
