Story about courage (5)

Ross

I believe the answer is:

fibre

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

'courage' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'story about' is the wordplay.
'story' becomes 'fib' (synonyms).
'about' becomes 're' ('re' means regarding or about).
'fib'+'re'='FIBRE'

Can you help me to learn more?

(Other definitions for fibre that I've seen before include "Long fine thread" , "Thread, filament" , "In brief, a thread" , "Brief (anag.)" , "Threadlike substance" .)
