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.
- Used in a sentence: We planned a surprise party for my dad.
- Used in a sentence: She couldn’t go hiking with us because she had already made plans to travel to California.
- 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
Origin of plan
First recorded in 1670–80; from French: “ground, plan, groundwork, scheme,” noun use of the adjective: “flat” ( see plane 1), a learned borrowing of Latin plānus “level” ( cf. plain 1)
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."
