Sc. and north. [Of obscure etymology.
The sense history of STEW sb.2 and the related vb. seems to exclude the possibility of connection with those words. From the similarity of sense, the word has been supposed to be cognate with (M)Du., LG. stof, OHG. stoup (mod.G. staub), Da. støv, dust; but the phonological possibility of this has not been shown]
Suffocating vapor, stench, or clouds of dust.
