IPA: /ˈbuːmtaʊn/
KK: /ˈbumˌtaʊn/
A town that is growing quickly in population and business due to economic success.
The new factory brought jobs and led to the development of a boomtown nearby.
Boomtown is formed from "boom" (from the Middle English "bome", meaning a loud noise or sudden increase) and "town" (from Old English "tun", meaning an enclosure or settlement). The word describes a town that experiences rapid growth, often due to economic prosperity or a sudden influx of people.
Think of a 'loud noise' ('boom') signaling a 'sudden increase' in population or activity in a 'settlement' ('town'). This helps you remember that a boomtown is a place that grows quickly.
