    Nouns ending in 'f' or 'fe' ,change "f"or "fe" into "v", and add "es"

    eg. calf - calves thief - thieves knife - knives wife - wives

    But some Exceptions:

    chief - chiefs cliff - cliffs dwarf - dwarfs hoof - hoofs gulf - gulfs

    proof - proofs roof - roofs safe - safes belief - beliefs

    Nouns ending in 'f' or 'fe', chnage 'f' or 'fe' into 'v', and add 'es'ed. calf - calves thief - thieves knife - knives wife - wives

    在英文文法中有一些rules是不可解釋的,只有死記,所以你知道由singular(單數) 'f'' 轉做plural(眾數) 'ves' ,你就耍記住,差不多所有都是一樣的.
