spine
|spine|
/spaɪn/
thorn / backbone
Etymology
'spine' originates from Latin, specifically the word 'spina', where 'spina' meant 'thorn' or 'backbone'.
'spina' passed into Old French as 'espine' and then into Middle English as 'spine', eventually becoming the modern English word 'spine'.
Initially it referred to a 'thorn' or 'pointed projection' and also 'a spine/backbone'; over time the anatomical sense ('backbone') and the figurative sense ('courage') became common in modern English.
