Etymology of "Threshold" [closed]

I found myself accidentally writing "threshhold" today, thinking semantically on the meaning.

Was there a time when "threshold" was spelt "threshhold"? Or is the etymology of this word really an esoteric combination of "thresh" and "old"?

Solution 1:

Does not seem to be a combination of individual words "thresh + hold", rather the other way around from these sources.

Source

Threshold," first recorded in the year 1000, descends from an Old English compound "threscold," "doorsill, point of entry."

Etymonline:

O.E. þrescold, þærscwold, þerxold "doorsill, point of entering," first element related to O.E. þrescan (see thresh), with its original sense of "tread, trample." Second element of unknown origin and much transformed in all the Germanic languages; in English it probably has been altered to conform to hold, but the oft-repeated story that the threshold was a barrier placed at the doorway to hold the chaff flooring in the room is mere folk etymology. Cognates include O.N. þreskjoldr, Swed. tröskel, O.H.G. driscufli, Ger. dial. drischaufel.

Word Origins

The first element of threshold is identical with English thresh (OE)... It is not known where the second element of threshold came from.
