a river in western Scotland that flows from the southern uplands into the Firth of Clyde; navigable by oceangoing vessels as far as Glasgow
"The historic ship sailed down the Clyde, navigating its deep waters from the Scottish uplands all the way to Glasgow."
A male given name transferred from the place name (the River Clyde in Scotland).
"Clyde was chosen as a boy's name because his parents wanted to honor the famous river in Scotland."
Clyde is named after a river in Scotland that takes its title from the Gaelic word Cluaidh, which has an unclear origin but may be linked to "clut," meaning the cleansing one. The name traveled into English directly through this Scottish geographical reference without changing its core identity as a place name.
