Bravery investing fortune in conifer plantations ultimately succeeded (10)
I believe the answer is:
pluckiness
'bravery' is the definition.
(I know that pluckiness is a type of fearlessness)
'fortune in conifer plantations ultimately succeeded' is the wordplay.
'fortune' becomes 'luck' (synonyms).
'in' means one lot of letters goes inside another.
'conifer' becomes 'pine' (pine tree is a type of conifer).
'ultimately' says to take the final letters.
'succeeded' becomes 's' (genealogical abbreviation).
The last letter of 'plantations' is 's'.
'luck' going within 'pine' is 'pluckine'.
'pluckine'+'s'+'s'='PLUCKINESS'
'investing' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Another definition for pluckiness that I've seen is " Courage".)
