Working so, I'm extremely respected - a titan in government (14)
I believe the answer is:
administration
'government' is the definition.
('administration' can be a synonym of 'government')
'working so i'm extremely respected a titan in' is the wordplay.
'working' indicates an anagram.
'extremely' says to hollow out the word (remove centre letters).
'respected' with its middle removed is 'rd'.
'so'+'im'+'rd'+'a'+'titan'+'in'='soimrdatitanin'
'soimrdatitanin' anagrammed gives 'ADMINISTRATION'.
(Other definitions for administration that I've seen before include "government in power" , "Running a business" .)
