'unreliably-linked' originates from the English word 'reliable,' with the prefix 'un-' indicating negation, and 'linked' from the Old English 'hlinc,' meaning 'a ridge or chain.'

'reliable' changed from the Old French word 'reliable,' meaning 'to be trusted,' and 'linked' evolved from the Old English 'hlinc,' eventually forming the modern English term 'linked.'

Initially, 'linked' meant 'a physical connection,' but over time it evolved to include abstract connections, such as data or ideas.
