Etymology
'armamentarium' originates from Latin, specifically the word 'armamentarium', where 'armare' meant 'to arm' and 'armamentum' meant 'equipment or implement.'
'armamentarium' passed through Medieval Latin with similar form and sense and entered English (recorded from the 17th century) as 'armamentarium', retaining the notion of equipment or apparatus.
Initially it referred to equipment for arming or military implements, but over time it evolved into the broader modern sense of 'a collection of tools, instruments, or resources for a particular purpose.'
