英文詞源
thus
thus: [OE] Thus is something of a mystery word. It presumably belongs to the family of words (that, there, etc) that go back to the prehistoric Germanic demonstrative base *tha-, but how its fits into the family tree is not clear. Its only close relative is Dutch dus ‘thus’.
thus (adv.)
Old English tus "in this way, as follows," related to t?t "that" and this; from Proto-Germanic *thus- (cognates: Old Saxon and Old Frisian thus, Middle Dutch and Dutch dus), from PIE *to-.
