Here's what we know:
* Esher is a town in Surrey, England, and the name is likely derived from the Old English words "æsc" (meaning "ash tree") and "hyrst" (meaning "wooded hill or copse").
* Therefore, Esher could be interpreted as "ash tree hill" or "wooded hill with ash trees".
It's also possible that the name was influenced by the River Mole, which flows through the town. "Mole" in Old English means "earth", and the river's name might have been derived from its meandering course through the landscape.
In summary, while the exact meaning of Esher is uncertain, it likely refers to a place characterized by ash trees and possibly a hilly terrain.
