Damn solution absorbing solver's head (5)
I believe the answer is:
curse
'damn' is the definition.
(I know that damn can be written as curse)
'solution absorbing solver's head' is the wordplay.
'solution' becomes 'cure' (I've seen this in another clue).
'absorbing' is an insertion indicator.
'head' suggests taking the first letters.
The first letter of 'solvers' is 's'.
'cure' placed around 's' is 'CURSE'.
(Other definitions for curse that I've seen before include "Profane or obscene expression" , "Excommunication" , "Execrate" , "Swear - oath" , "Evil spell - oath" .)
