Pronunciation: [sˈandbaŋk] (IPA) 
The word "sandbank" is spelled with an "a" in the first syllable instead of an "e" due to the phonetic transcription of the word. In IPA, the first syllable is transcribed as /sænd/, which uses the "a" sound (æ) as opposed to the "e" sound (ɛ). The second syllable is transcribed as /bæŋk/, with both syllables using the "a" sound. A sandbank is a ridge of sand that forms in a body of water, typically near the shore.
A sandbank refers to a narrow stretch of accumulated sand or sediment that rises above the water level in a body of water, such as a river, lake, or ocean. This natural formation is typically found in shallow areas and is marked by its gentle slope or rise from the surrounding water.
Sandbanks are usually formed as a result of the deposition and accumulation of sand or other granular material carried by water currents or waves. These sediment deposits gradually build up over time, often due to the influence of tides or river flow, creating a barrier or ridge above the water surface.
Sandbanks can vary greatly in size, shape, and extent. While some may span only a few meters, others can extend for many kilometers. They can be found along coastlines, where they contribute to the formation of beaches, or in water bodies like rivers and lakes.
These geographical features play a significant role in coastal ecosystems as they provide essential habitats for various marine organisms. Sandbanks often support diverse communities of plants and animals, including burrowing creatures, shellfish, and algae, which use the sand as a substrate or a source of nutrients. In addition, sandbanks also act as natural barriers, helping to protect shorelines from erosion caused by wind, waves, and currents.
The word "sandbank" is derived from the combination of two separate words: "sand" and "bank".
The word "sand" originates from the Old English word "sund" which can be traced back to the Proto-Germanic word *sundaz. This word refers to fine, granular particles of worn-down rock or minerals found on the seashore, deserts, or riverbeds.
The word "bank" comes from the Old Norse word "bakk", which has the same meaning. It relates to the idea of an elevated or raised mound of land. Later, the Old English word "banca" integrated "bakk" and adopted the meaning of a mound of earth or raised ridge.
