The word "two-way" consists of two components: "two" and "way".
"Two" originates from the Old English word "twā", which is derived from the Proto-Germanic word "twai". This word has roots in the Proto-Indo-European language, with the root "dwo", meaning "two". Throughout various Germanic languages, such as Dutch "twee" and German "zwei", the word has evolved while retaining its fundamental meaning.
The term "way" comes from the Old English word "weg", which is related to the Old Norse "vegr" and the Old High German "weg", all meaning "path" or "journey". Its Proto-Indo-European root is "wegh-", conveying the concept of "go" or "move".
