  • Syn: Burden, Load.
  • Usage: 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. [1913 Webster]
