Etymology: "Sithen" is an archaic English word meaning "since" or "afterwards," and it is the older form of the word "since" itself. It descends from Old English "siþþan," which combined "sīþ," meaning "since," with "þǣm," meaning "that." Put together, the two pieces meant roughly "since that," and the word gradually took on the sense of a span of time running from a past point until now. The same word survives in neighbouring Germanic languages. German "seitdem" and Old Norse "síðan" share this ancestry, so the Old English word was part of a family of time words spoken across the North Sea and Scandinavia. English eventually shortened the form, and "since" replaced "sithen" in everyday use, though "sithen" lingered for centuries in Middle English writing.
