Inquirer ekes out sign of hesitation (6)
I believe the answer is:
seeker
'inquirer' is the definition.
(someone seeking answers)
'ekes out sign of hesitation' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'sign of hesitation' becomes 'er'.
'ekes' is an anagram of 'seek'.
'seek'+'er'='SEEKER'
(Other definitions for seeker that I've seen before include "(Missile) target searcher" , "One attempting to find" , "Inquirer; quester" , "member of pop group down under ..." , "One who pursues and searches for" .)
