a tombolo is a spit that joins the mainland to an island
It is called an isthmus.
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 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.

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".)
Sand spits form when elongated sandbars remain in place due to wave action along a shoreline. The spit can remain attached to the shore as an isthmus, or a bar can be separated to form a barrier island. Tombolos can create the same form but in the opposite manner. An island near the shore accumulates sandbars in the separating strait, and can become a "tied island" when the tombolo creates a permanent land bridge.
What is a Tombolo?
A tombolo, from the Italian tombolo, derived from the Latin tumulus, meaning 'mound,' and sometimes translated as ayre (Old Norse eyrr, meaning 'gravel beach'), is a deposition landform in which an island is attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island. Several islands tied together by bars which rise above the water level are called a tombolo cluster.[1] Two tombolos can form an enclosure (called a lagoon) that can eventually fill with sediment.

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.
