Mind getting a little tipsy? Cheers! (6)
I believe the answer is:
psyche
'mind' is the definition.
(I know that mind can be written as psyche)
'a little tipsy? cheers' is the wordplay.
'a little' indicates a hidden word.
'PSYCHE' is hidden in the letters of 'tipsy cheers'.
'getting' acts as a link.
(Other definitions for psyche that I've seen before include "The human mind/spirit" , "Soul, spirit; lover of Cupid" , "Human soul or spirit" , "Eros's beloved" , "The soul, spirit or mind" .)
