Forms

siþþan[1]

Etymology

It is formed from Old English sīþ (“later”) + þon (“than that”), from an unrecorded phrase meaning “later than that”, contracted, with the long vowel shortened.[1][2] Bosworth and Toller derive it from sīþ with the dative ðam, and compare German seitdem.[3] Köbler lists the adverb and the conjunction under the comparative adverb sīþ.[4]

Early West Saxon writes ⟨siððan⟩, late West Saxon ⟨syþþan⟩;[5] Kentish texts also have ⟨seoððan⟩ and ⟨sioððan⟩ with back umlaut, beside ⟨siððan⟩ in the Kentish charters S 1195 and S 1200.[5] The MED lists Mercian ⟨seoððan⟩ and a shortened Northumbrian ⟨soðða⟩.[6]

Earliest recorded meaning

The word is first recorded in a Kentish charter of about 850 (S 1195), held to be a contemporary original: Ealhburg asks her kinsman Eadweald to keep the render his dei & siððan forð bebeode his erbum to healdenne, “in his day, and afterwards to bid his heirs keep it”.[7][8]

Semantic evolution

As an adverb it means “afterwards, then, from then on”, and with ā or ǣfre “ever after”; as a conjunction it means “after, since, when, as soon as”, sometimes shading into “because”.[3][2] Clauses can be paired, siþþan … siþþan “when … then”, as in the Old English Orosius.[9] In the laws it means “henceforth” and introduces the main clause after a conditional one.[10] It glosses Latin postquam, deinde and dehinc.[4]

It became Middle English sitthen, now dialectal English sithen, and with an added -s Middle English sitthens, the source of English since.[6][1]
