🇬🇧
/nɒnˈvɛzɪkjʊlə/
not having vesicles (small sacs/blisters)
Etymology
'non-vesicular' originates from English, formed by the prefix 'non-' (meaning 'not') attached to 'vesicular', where 'vesicular' comes from Latin 'vesicula' meaning 'small bladder' or 'little sac'.
'vesicular' comes from Latin 'vesicula' (a diminutive of 'vesica' meaning 'bladder' or 'blister'); English formed 'vesicular' to mean 'having vesicles', and modern English formed 'non-vesicular' by adding the productive negative prefix 'non-'.
Initially, the Latin root referred to a physical 'bladder' or 'blister'; over time it gave rise to the adjective 'vesicular' meaning 'having small sacs or blisters', and 'non-vesicular' developed to denote the absence of such sacs or blisters.
