Now the carides were so called from the word κόρα, head. For the head takes up the greater part of them. But the Attic writers also use the word short in the same manner, in analogy with the quantity of κάρα, it being, as I said, called cars because of the size of its head; and so, as γραφὶς is derived from γραφὴ, and βολὶς from βολὴ, in like manner is καρὶς from κάρα. But when the penultima is made long the last syllable also is made long, and then the word is like ψηφὶς, and κρηπὶς, and τευθίς.
