v. (past sg.)
WA pres. 3 sg. silis, pres. pl. silis, pres. ptcp. syland
'go, pass (on)'(Modern English )
The etymology of this rare v. is obscure, but it is usually compared with Norw and Sw dial sila 'flow' and thus a Scandinavian origin is assumed to be most plausible, though it remains entirely speculative (so e.g. OED, MED). The pattern of attestation may be taken to support this possibility, but it is circumstantial. The v. may or may not be identical with ME sīlen 'strain', cp. Norw and Sw sila 'strain', derived from a n. (cp. Sw sīl 'strainer') formed on the PGmc v. *sīxwan- 'filter' (cp. OIcel sía, OFris sīa, OE sēon 'strain, filter', MDu sien 'drip', OHG sīhan 'strain').
