Usage

What is a basic definition of plan? A plan is a program or method prepared ahead of time, a project or definite purpose, or a design or drawing of something. Plan has several other senses as a noun and a verb. When you come up with a plan, you are creating a method or scheme to do something, make something, or take another kind of action, like a plan for getting your homework done. If someone does something without thinking about what to do, how to do it, and when to do it, they don’t have a plan. A plan doesn’t have to be written down, though. It may only exist in your mind. A person who comes up with a plan is a planner.

• Real-life examples: Your school very likely has a plan for everyone leaving the building if there is a fire. Criminals often come up with a plan  of how they will steal something and when so that they will know what to do and be able to leave quickly.
• Used in a sentence: The prisoners needed hot air balloons for their elaborate escape plan. 

Plan is used in this same sense as a verb to mean to scheme something ahead of time.

• Used in a sentence: We planned a surprise party for my dad. 

Plan can also mean a project or definite purpose that someone has thought about or has scheduled to happen. In this sense, it is often used in the plural as plans.

• Used in a sentence: She couldn’t go hiking with us because she had already made plans to travel to California.

Plan is also used as a synonym for diagram and blueprint. A plan of a warehouse, for example, will likely include drawings of the building’s layout or an outline of where wiring and pipes are located within the walls. Usually, an architect or designer will draw up a plan of a building or prototype so that the builders will know what to do.

• Used in a sentence: The fire chief got the building plan from the janitor, so he could find the circuit breaker.

Synonym Usage

Plan, project, design, scheme imply a formulated method of doing something. Plan refers to any method of thinking out acts and purposes beforehand: What are your plans for today? A project is a proposed or tentative plan, often elaborate or extensive: an irrigation project. Design suggests art, dexterity, or craft (sometimes evil and selfish) in the elaboration or execution of a plan, and often tends to emphasize the purpose in view: a misunderstanding brought about by design. A scheme is apt to be either a speculative, possibly impracticable, plan, or a selfish or dishonest one: a scheme to swindle someone.

Etymology

Explanation

Do you have an idea of what you want and have thought carefully and in detail about how to get it? Then you have a plan, a series of actions required to achieve a particular goal. A plan can exist only in your head, or it can be a physical object, such as an architectural plan of a building, showing how you propose to build it. As a verb, plan means the act of thinking about how to achieve your aims. You might plan to apply to colleges soon. When you plan something, you're laying the seeds for a future result, so it's not surprising that plan comes from the early English word plante, meaning "seedling."
