* Grape-like clusters: The most common theory is that the name comes from the fruit's tendency to grow in clusters resembling bunches of grapes.
* Size and shape: Some argue that the name refers to the grapefruit's size, which is similar to a large grape.
* Early misidentification: There's a possibility the fruit was initially confused with a type of grape, leading to the name.
It's important to note that "grapefruit" wasn't the fruit's original name. Early settlers in Barbados called it the "shaddock," after Captain Shaddock, who supposedly introduced the fruit to the West Indies.
While the origin of "grapefruit" remains somewhat uncertain, the name has stuck and is now widely recognized.
