Stimulate with tale about the Orient (5)
I believe the answer is:
elate
'stimulate' is the definition.
(elating is a kind of stimulating)
'with tale about the orient' is the wordplay.
'with' is a charade indicator (letters next to each other).
'about' indicates anagramming the letters.
'the orient' becomes 'e' (**).
'tale' anagrammed gives 'elat'.
'elat'+'e' is 'ELATE'.
(Other definitions for elate that I've seen before include "Make ecstatically happy" , "Make joyful and proud" , "Fill with optimism" , "transport?" , "Excite" .)
