Here are some Wikipedia links on Latin, English, Anglo-Saxon... Hopefully these will prove useful as I think through my introductory lessons for next year. I want the students to be able to see the profound influence historical events have on the formation of language.
Dual number (not directly related to Latin, but adaptable given the declensions of duo and ambo)
Old English (and how it was influenced by Latin, etc, to become modern English)
Yogh (Interesting article on why night, cough, through all have different 'gh' sounds)
Eth (again, why 'th' is pronounced as it is)
Wynn (runic beginnings of our 'W')
Germanic and Latinate Equivalents (Excellent list of words and roots)
Latin Proverbs (use as quotes)
