Usage

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. Throughout history, people have rebelled against the bonds of tyranny, that is, oppression of a government they think is unfair or unjust.
• Used in a sentence: We freed the prisoners from their metal bonds. 

This sense of bond is also used as a verb to mean to bind things together.

• Used in a sentence: The welder bonded the steel sheets to each other. 

In a similar sense, bond is used in chemistry to refer to an attraction between atoms that hold them together to form molecules. These are also known as chemical bonds and they are a very important concept to molecular chemistry.

• Real-life examples: Chemical bonds are further divided into specific kinds of bonds that hold molecules together. Different types of bonds include covalent bonds, ionic bonds, hydrogen bonds, coordinate bonds, and metallic bonds.
• Used in a sentence: Professor Smith used a model to show us the bonds between atoms in a molecule of ammonia. 

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.

• Real-life examples: You are connected to your family and friends by a close bond. You may also form close bonds with your pet. Countries that are allies have a close bond and usually promise to help or protect each other.
• Used in a sentence: John and Paul have a strong bond of friendship and they think of each other as brothers. 

Closely related to this sense, bond is used as a verb to mean to form a strong emotional relationship with someone.

• Used in a sentence: I bonded with my father during the many fishing trips we went on together. 

Synonym Usage

Bond, link, tie agree in referring to a force or influence that unites people. Bond, however, usually emphasizes the strong and enduring quality of affection, whereas tie may refer more especially to duty, obligation, or responsibility: bonds of memory; Blessed be the tie that binds; family ties. A link is a definite connection, though a slighter one; it may indicate affection or merely some traceable influence or desultory communication: a close link between friends.

Explanation

You and your best friend have a bond that allows you to trust each other with all your thoughts and secrets. A bond is a connection between two things. Bond can refer to a physical or emotional restraint as in a prisoner who might tear off his bonds and escape to freedom. If you are arrested, your parents will have to pay a bond to get you released from jail. If you don't show up to court, they will lose that money. A certificate of debt issued by a government or corporation is also called a bond. When you cash in the bond on a set date, you get your money back plus interest. In its meaning of "connection," bond can be used as a verb. Have you ever met someone and felt an instant connection? You can say that you bonded.
