Note 1 — Front matter
Reading edition
The most noticeable difference in pronunciation, the Castilian guttural soft G and J, and the lisping of the Z or soft C seems to be of comparatively modern origin. However different such words as 'chave' and 'llave,' 'filho' and 'hijo,' 'mão' and 'mano' may seem they are really the same in origin and derived from clavis, filius, and manus.
