Stormy, eccentric, blunt and true (9)
I believe the answer is:
turbulent
'stormy' is the definition.
(similar in meaning)
'eccentric blunt and true' is the wordplay.
'eccentric' is an anagram indicator.
'and' says to put letters next to each other.
'blunt' after 'true' is 'trueblunt'.
'trueblunt' with letters rearranged gives 'TURBULENT'.
(Other definitions for turbulent that I've seen before include "Let tub run, being in state of commotion" , "rough" , "raging" , "Troublesome" , "Stormy" .)
