'non-pulmonary' originates from Latin, specifically the word 'pulmonarius,' where 'pulmo' meant 'lung.' The prefix 'non-' is used to indicate negation or absence.

'pulmonarius' transformed into the English word 'pulmonary,' and with the addition of the prefix 'non-,' it became 'non-pulmonary.'

Initially, 'pulmonarius' meant 'related to the lungs,' and with the prefix 'non-,' it evolved to mean 'not related to the lungs.'
