Feverish, tearful end to supplicant’s squirming (8)
I believe the answer is:
aflutter
'feverish' is the definition.
(both can mean very excited)
'tearful end to supplicant's squirming' is the wordplay.
'end to' indicates one should take the final letters.
'squirming' indicates anagramming the letters (I've seen this in other clues).
The final letter of 'supplicant' is 't'.
'tearful'+'t'='tearfult'
'tearfult' anagrammed gives 'AFLUTTER'.
(Other definitions for aflutter that I've seen before include "trembling" , "Nervous, twitchy" , "is rather nervous" , "in excited state" , "Agitated - excited (eg in anticipation)" .)
