'purine' originates from German, specifically the word 'Purinstoff,' where 'pur-' meant 'pure' and '-in' was a common suffix for chemical substances.

'Purinstoff' transformed into the English word 'purine,' and eventually became the modern English word 'purine-related' by adding the suffix '-related.'

Initially, it meant 'pure substance,' but over time it evolved into its current meaning of 'related to purine.'
