Yet though the English conquered the Britons, the two peoples could not have mixed much or married very often with each other; for if they had done so, many more British words would have been borrowed by the English language. To the English the Britons were strangers and "slaves." We could, too, guess some of the things which these old English conquerors of Britain did and believed from examining some common English words. If we think of the days of the week besides _Sunday_, or the "Sun's day," and _Monday_, the "Moon's day," we find _Tuesday_, "Tew's day," _Wednesday_, "Woden's day," _Thursday_, "Thor's day," _Friday_, "Freya's day," _Saturday_, "Saturn's day," and it would not be hard to guess that most of the days are called after gods or goddesses whom the English worshipped while they were still heathen, Tew was in the old English religion the bravest of all the gods, for he gave up his own arm to save the other gods. Woden, the wisest of the gods, had given up not an arm but an eye, which he had sold for the waters of wisdom. Thor was the fierce god of thunder, who hurled lightning at the giants. Freya was a beautiful goddess who wore a magic necklace which had the power to make men love. We might then guess from the way in which our old English forefathers named the days of the week what sort of gods they worshipped, and what kind of men they were--great fighters, admiring courage and strength above all things, but poetical, too, loving grace and beauty. But, as everybody knows, the English people soon changed their religion and became Christians; and any student of the English language would soon guess this, even if he knew nothing of English history. He would be able to guess, too, that the English got their Christianity from a people who spoke Latin, for so many of the English words connected with religion come from the Latin language. It was, of course, the Roman monk St. Augustine who brought the Christian religion to the English. Latin was the language of the Romans. The word _religion_ itself is a Latin word meaning reverence for the gods; and _Mass_, the name given to the chief service of the Catholic religion, comes from the Latin _missa_, taken from the words, _Ite missa est_ ("Go; the Mass is ended"), with which the priest finishes the Mass. _Missa_ is only a part of the verb _mittere_, "to finish." The words _priest_, _bishop_, _monk_, _altar_, _vestment_, and many others, came into the English language from the Latin with the Christian religion. Even, again, if a student of the English language knew nothing about the invasions of England by the fierce Danes, he might guess something about them from the fact that there are many Danish words in the English language, and especially the names of places. Such common words as _husband_, _knife_, _root_, _skin_, came into English from the Danish.
