Fable about ill wind that's liable to fail (8)

I believe the answer is:

fallible

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

'liable to fail' is the definition.
I can't tell whether this definition defines the answer.

'fable about ill wind' is the wordplay.
'about' means one lot of letters goes inside another.
'wind' indicates an anagram.
'ill' anagrammed gives 'lli'.
'fable' placed around 'lli' is 'FALLIBLE'.

'that's' acts as a link.

Can you help me to learn more?

(Other definitions for fallible that I've seen before include "Likely to fail or make errors" , "Liable to err" , "Capable of making mistakes" , "Bali fell (anag)" , "Northern Scandinavian" .)
