Another versatile word which has a bit of an antiquated feel to it. In familiar, non-topical contexts (which is my main focus— see definition three), this verb is rarely seen. I say we bring it back and put it into good use once more!

Etymology: from O.E. bilecgan, which, among other senses, meant “to lay a thing about” (with other objects), from be- + lecgan “to lay” (see lay). The only surviving sense is the nautical one of “coil a running rope round a cleat or pin to secure it” (also transferred to mountain-climbing), first attested 1540s; but this is possibly a cognate word, from Du. beleggen.
