Hopelessness entering Dr Matt Fink's second letters on psychic power (7)
I believe the answer is:
despair
'hopelessness' is the definition.
(despair is a kind of hopelessness)
'second letters on psychic power' is the wordplay.
'second' becomes 'd'.
'letters' becomes 'air' (air letter is a kind of letter).
'on' is a charade indicator (letters next to each other).
'psychic power' becomes 'esp' (abbreviation for extrasensory perception).
'air' after 'esp' is 'espair'.
'd'+'espair'='DESPAIR'
'entering dr matt fink's' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for despair that I've seen before include "Smashed up" , "First appearance" , "Feeling of hopelessness" , "Give up hope" , "Resignation" .)
