| burden | 1. To encumber with weight (literal or figurative); to lay a heavy load upon; to load. "I mean not that other men be eased, and ye burdened." (2 Cor. Viii. 13) 2. To oppress with anything grievous or trying; to overload; as, to burden a nation with taxes. "My burdened heart would break." (Shak) 3. To impose, as a load or burden; to lay or place as a burden (something heavy or objectionable). "It is absurd to burden this act on Cromwell." (Coleridge) Synonym: To load, encumber, overload, oppress. Origin: Burdened; Burdening. 1. That which is borne or carried; a load. "Plants with goodly burden bowing." (Shak) 2. That which is borne with labour or difficulty; that which is grievous, wearisome, or oppressive. "Deaf, giddy, helpless, left alone, To all my friends a burden grown." (Swift) 3. The capacity of a vessel, or the weight of cargo that she will carry; as, a ship of a hundred tons burden. 4. <chemical> The tops or heads of stream-work which lie over the stream of tin. 5. <chemistry> The proportion of ore and flux to fuel, in the charge of a blast furnace. 6.

Burden of proof, the duty of proving a particular position in a court of law, a failure in the performance of which duty calls for judgment against the party on whom the duty is imposed. Synonym: Burden, Load. A burden is, in the literal sense, a weight to be borne; a load is something laid upon us to be carried. Hence, when used figuratively, there is usually a difference between the two words. Our burdens may be of such a nature that we feel bound to bear them cheerfully or without complaint. They may arise from the nature of our situation; they may be allotments of Providence; they may be the consequences of our errors. What is upon us, as a load, we commonly carry with greater reluctance or sense of oppression. Men often find the charge of their own families to be a burden; but if to this be added a load of care for others, the pressure is usually serve and irksome. Origin: OE. Burden, burthen, birthen, birden, AS. Byrthen; akin to Icel. Byrthi, Dan. Byrde, Sw. Borda, G. Burde, OHG. Burdi, Goth. Baorei, fr. The root of E. Bear, AS. Beran, Goth. Bairan. 92. See 1st Bear.
