Parched doctor to die perhaps (5)
I believe the answer is:
dried
'parched' is the definition.
(I've seen this before)
'doctor to die perhaps' is the wordplay.
'doctor' becomes 'Dr' (abbreviation).
'perhaps' is an anagram indicator.
'die' with letters rearranged gives 'ied'.
'dr'+'ied'='DRIED'
(Other definitions for dried that I've seen before include "Forgot words (on stage)" , "Preserved, in a way" , "Like clean dishes" , "Desiccated" , "With moisture removed" .)
