'virology' originates from the Latin word 'virus,' meaning 'poison' or 'slimy liquid,' combined with the Greek suffix '-logy,' meaning 'study of.'

'virus' transformed from the Latin word 'virus' into the modern English word 'virus,' and eventually combined with '-logy' to form 'virology.'

Initially, 'virus' meant 'poison' or 'slimy liquid,' but over time it evolved into its current meaning of 'a microscopic infectious agent.'
