This is the definition of a "barrier spit".
(A tombolo is a sandbar that connects the mainland to an island, forming a permanent or temporary isthmus, and the island can be known as a "tied island".)
Tombolo's are ridges of sand and shingle which join the mainland to an island. Tombolo's are created through the process of longshore drift. Where there is a change in the shape of the land, a spit forms in the shallow / sheltered water. A tombolo is formed where the spit continues to grow until it reaches an island, forming a link with the mainland
A tombolo is a sandbar that connects the mainland to an island, forming a permanent or temporary isthmus, and the island can be known as a "tied island". Tombolos form from sand or sediment pushed along a shoreline.
I am not entirely sure, but I think it may have to do with the connecting mass. Tombolos are usually connected by a sandbar, which is more prone to geographical effects and can be more effected by waves and tides. Peninsulas are connected by more "solid" land masses such as solid ground that are not as prone to being shifted around. Also, peninsulas have to be connected to a mainland, whereas tombolos can be connected to other islands as well as a mainland.
They're known as spits, if they are merely pieces of land unattached to a second island. However, when they become attached, they form a tombolo.

What is a Tombolo?
A spit and a tombolo are both landforms that extend into a body of water. The difference is that a spit is typically connected to land at one end and extends into the water, while a tombolo connects an island to the mainland. Both features are formed by sediment deposition and can change over time due to natural processes like erosion and sediment transport.

Some landforms made by deposition include beaches, sand dunes, alluvial fans, and deltas. These landforms are created as sediment is carried by wind, water, or ice and deposited in a new location.
It is called an isthmus.
