Extremely feeble, suffering shiver?! (8)

I believe the answer is:

feverish

I'm a little stuck... Click here to teach me more about this clue!

'extremely feeble suffering shiver?' is the definition.
The answer and definition are not the same part of speech.

'extremely feeble suffering shiver?' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'suffering' indicates anagramming the letters.
'feeble' with its middle taken out is 'fe'.
'shiver' anagrammed gives 'verish'.
'fe'+'verish'='FEVERISH'

Can you help me to learn more?

(Other definitions for feverish that I've seen before include "Suffering from a high temperature" , "frantic" , "Restlessly excited" , "hectic" , "Febrile" .)

I've seen this clue in the Sydney Morning Herald.
