'individually-backed' originates from the combination of 'individual' and 'backed', where 'individual' comes from Latin 'individuus', meaning 'indivisible', and 'backed' is derived from the Old English 'bæc', meaning 'support'.

'individually-backed' evolved from the concept of individual support, combining the modern English words 'individual' and 'backed'.

Initially, it meant 'supported by a single person', but over time it evolved to mean 'supported by multiple individuals'.
