Tipsy chef's hidden spirit (6)
I believe the answer is:
psyche
'spirit' is the definition.
(psyche is a kind of spirit)
'tipsy chef's hidden' is the wordplay.
'hidden' indicates a hidden word.
'PSYCHE' is hidden within 'tipsy chefs'.
(Other definitions for psyche that I've seen before include "Princess beloved by Cupid" , "Core of one's personality" , "Human soul, or its personification in female form" , "Eros's beloved" , "A beautiful girl" .)
