Ait

An ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/) is a small island. It is especially used to refer to river islands found on the River Thames and its tributaries in England.^[1][2][3]

Aits are typically formed by the deposit of sediment in the water, which accumulates. An ait is characteristically long and narrow, and may become a permanent island should it become secured and protected by growing vegetation. However, aits may also be eroded: the resulting sediment is deposited further downstream and could result in another ait. A channel with numerous aits is called a braided channel.^[3]
