'Amman' originates from the ancient Semitic language, specifically the word 'Rabbath Ammon,' where 'Rabbath' meant 'great' and 'Ammon' referred to the Ammonite people.

'Rabbath Ammon' transformed into the Arabic word 'Amman,' and eventually became the modern English name 'Amman.'

Initially, it referred to the 'great city of the Ammonites,' but over time it evolved into its current meaning as the capital of Jordan.
