Interestingly, although I speak no Portuguese or French, I can sort of understand some of the sayings, by mentally translating them back in a literal way to Spanish.

For example "Few few the bird make her nest" probably means "Bit by bit a bird builds a nest". "A horse baared don't look him in the tooth" is probably "Don't look a gift horse in the mouth", via the Spanish version "A caballo regalado no se le miran los dientes".

I can probably make sense of half of them. The other half are hilariously mangled beyond recognition :)
