What does soth mean?
Soth is an archaic English noun for soot. It refers to the fine, black residue produced by the incomplete burning of wood, coal, oil, or other fuels, particularly the deposit left in chimneys, fireplaces, and flues. Although historically understandable and encountered in older writing, the word has virtually disappeared from ordinary modern English, where soot is used instead. Soth can occasionally give a period atmosphere to historical fiction, descriptions of old buildings, or quotations from early texts, but using it in everyday speech is likely to sound deliberately antiquarian or regional. The word is not normally used to refer to smoke itself: the material called soth is the dark combustible residue left after burning, rather than the visible gaseous or airborne substance. Its unusual spelling also distinguishes it from sooth, an unrelated archaic word for truth. Overall, soth is chiefly significant as a historical form preserved in the vocabulary of earlier English.

Where does soth come from?
Soth descends from Old English sōþ, meaning “soot,” in which þ represented the voiceless dental fricative now written th. The form continued in Middle English and survived in later archaic and dialectal usage. Its modern counterpart, soot, reflects the standard English development of the same inherited word, while related forms include sooty and sooted.
