Load, n.
A burden; that which is laid on or put in any thing for conveyance. Thus we lay a load on a beast or on a man's shoulders, or on a cart or wagon; and we say, a light load, heavy load. A load then is indefinite in quantity or weight. But by usage, in some cases, the word has a more definite signification, and expresses a certain quantity or weight, or as much as is usually carried, or as can be well sustained.
