மலேரியா (Tamil)

Where does "மலேரியா" come from?

The Tamil word 'மலேரியா' is borrowed from the English 'malaria', which traces back to the Italian phrase 'mala aria', meaning 'bad air'. This reflects the historical belief that the disease was caused by the foul-smelling vapors of swamps rather than mosquitoes. Ultimately, these roots descend from Latin and Ancient Greek words for 'bad' and 'air', with the later stemming from a Proto-Indo-European root meaning 'to dawn' or 'become light'.
