The word "so then" is a phrase commonly used in English to express a logical or sequential conclusion. However, it is not considered a single-word term but rather a combination of two separate words. Here is a breakdown of their etymologies:
1. So: The word "so" originated from the Old English word "swā", which means "in that way" or "thus". It can be traced back to the Proto-Germanic language, where it had a similar form. The Proto-Germanic term further evolved from the Proto-Indo-European root *swo- or *se- meaning "this" or "that". Over time, "so" came to be used to denote a manner, degree, or consequence in English.
2. Then: The word "then" also has Old English origins, derived from the word "þanne" or "ðonne".
