What is a basic definition of bond?

A bond is something that binds or fastens things together, something that unites people, or an attraction between atoms in a molecule. Bond has many other senses as a noun and a verb.

Bond can refer to anything that holds or links things together. For example, glue is commonly used as a bond to make things stick to each other. Bond is often used in the plural when referring to things like shackles or handcuffs that bind multiple parts of the body. In this sense, bond is often used figuratively to refer to things that bind or restrict a person’s liberty or freedom.

  • Real-life examples: Glue, rope, zip ties, cables, pins, and staples are examples of things used as bonds. Prisoners are often kept in bonds, like chains, handcuffs, and shackles, to prevent them from escaping.

Bond is also used in a figurative sense to refer to agreements or relationships that unite people. In this sense, bond often specifically refers to an especially close or trusting relationship.

Cultural definitions for bond


A security issued by a corporation or public body and usually carrying a fixed rate of interest and a set date, called the bond's maturity, for redemption of the principal. Like a stock, a bond is a type of investment, but unlike a stock, a bond has a definite, but not necessarily fixed, yield. Some bonds have a feature known as a call, which gives the borrower an option to pay off the principal of the bond before its maturity, the date when the bond is due to be redeemed. (See municipal bonds and Treasury bills.)
