Etymology
Etymology Information

'antiviral' originates from modern English, a combination of the prefix 'anti-' (meaning 'against') and the adjective 'viral' (relating to a 'virus').

Historical Evolution

'viral' derives from the noun 'virus', from Latin 'virus' meaning 'poison' or 'venom'; 'antiviral' was formed in English in the 20th century by combining 'anti-' with 'viral' to name agents acting against viruses.

Meaning Changes

Initially the components meant 'against' ('anti-') and 'poison/virus' (via 'virus'), and over time 'antiviral' came to mean specifically 'acting against viruses' or 'a drug that acts against viruses'.
