Full Definition of GERANIUM
: any of a widely distributed genus (Geranium of the family Geraniaceae, the geranium family) of plants having regular usually white, pink, or purple flowers with elongated styles and glands that alternate with the petals —called also cranesbill
Many of the plants of the geranium family have long, thin, pointed fruits that look a bit like the bill of a bird. The ancient Greeks thought that the fruit of the wild geranium looked like the bill of a crane, and so gave the plant the name geranion, literally, “little crane.” The English word geranium came from this Greek name.
