'aneurine' originates from a combination of 'a-' (not) and 'neurine' (a compound found in nerve tissue), indicating its importance in nerve function.

'aneurine' was coined in the early 20th century as a name for vitamin B1, before 'thiamine' became the more common term.

Initially, it referred specifically to vitamin B1, and this meaning has remained unchanged, though 'thiamine' is now more commonly used.
