noun
peninsula
puh-NIN-suh-luh/pəˈnɪnsələ/
Land almost surrounded by water but connected to a larger landmass.
The peninsula joins the mainland by a neck while water surrounds three sides.

Etymology
A peninsula is literally “almost an island”: water nearly surrounds it, but its connection to a larger landmass keeps it from being a true island.
In context
When we think of Italy in antiquity, we invariably think of the Romans, a people needing no explanation, who grew to dominate not only this peninsula, jutting out into the water of the Mediterranean
More examples

- We can see the lake from both sides of the peninsula.
