'jeer' originates from Dutch, specifically the word 'gieren,' where 'gieren' meant 'to cry or shout.'

'gieren' transformed into the English word 'jeer' during the 16th century, and eventually became the modern English word 'jeer.'

Initially, it meant 'to cry or shout,' but over time it evolved into its current meaning of 'mocking or scornful shouting.'
