'nonattender' originates from the prefix 'non-' meaning 'not' and the word 'attend' from Latin 'attendere', where 'ad-' meant 'toward' and 'tendere' meant 'to stretch'.

'attendere' transformed into the Old French word 'atendre', and eventually became the modern English word 'attend'. The prefix 'non-' was added to form 'nonattender'.

Initially, 'attend' meant 'to stretch toward', but over time it evolved into its current meaning of 'to be present at'. 'Nonattender' specifically refers to someone who is not present.
