fortaleza (Portuguese)
Where does "fortaleza" come from?
The Portuguese word 'fortaleza' stems from the Latin 'fortis,' meaning 'strong,' which traces back to ancient roots potentially relating to being firm or high. It evolved through Late Latin into 'fortalitia' before passing through Old Occitan as 'fortalessa.' This history illustrates how the concept of physical fortification grew to encompass the emotional fortitude and inner strength that define the word's usage today.
