Fortitude shown in personal column? (8)
I believe the answer is:
backbone
This might be a double definition.
'fortitude' is the first definition.
(backbone is a kind of fortitude)
'personal column?' is the second definition.
'backbone' can be an answer for 'column?' (I have seen 'Spinal column ' mean 'backbone' so perhaps 'column' could also mean 'backbone'). I am not certain of the 'personal' bit.
'shown in' acts as a link.
Can you help me to learn more?
(Other definitions for backbone that I've seen before include "Lt protects the spinal cord" , "Firmness of character" , "Steel" , "Strength of character" , "Spine or courage" .)
