Isthmus is a narrow strip of land that connects two larger landmasses and separates two bodies of water. It is essentially a land bridge. Examples of isthmuses include the Isthmus of Panama, which connects North and South America, and the Isthmus of Suez, which connects Africa and Asia.

Strait, on the other hand, is a narrow waterway that connects two larger bodies of water and separates two landmasses. A strait can be thought of as a narrow channel that allows water to flow between two larger bodies of water. Examples of straits include the Strait of Gibraltar, which separates Europe and Africa, and the Bosphorus Strait, which separates Europe and Asia.

Isthmuses are narrow strips of land, while straits are narrow waterways.
