What is another word for carob bean tree?
Pronunciation: [kˈaɹɒb bˈiːn tɹˈiː] (IPA) 
The carob bean tree, also known as Ceratonia siliqua, has a variety of synonyms in the plant world. One of these synonyms is St. John's bread, which is derived from the biblical story that John the Baptist survived in the wilderness by eating the tree's pods. The tree is also sometimes called locust bean, although it is not related to the insect at all. In some Mediterranean countries, the tree is known as algarrobo or algarroba. The word carob itself comes from the Arabic word "kharrub," which means pod, as the tree's bean-shaped pods are the primary part of the plant used in cooking and manufacturing.
