Century Dictionary and Cyclopedia

1. n. The representation of anything drawn on a plane, as a map or chart; specifically, the representation of a building or other structure in horizontal section, as it stands or is intended to stand on the ground, showing its extent, and the division and distribution of its area into apartments, rooms, passages, etc., or its method of construction and the relation of its parts. The raised plan of a building is the same as an elevation. A geometricul plan is one drawn to scale, or one in which the solid and vacant parts are represented in their natural proportions. A perspective plan is one the lines of which follow the rules of perspective, thus showing more distant parts smaller than they are in fact in relation to the nearer parts. The term plan may be applied to the draft or representation of any projected work on paper or on a plane surface: as, the plan of a town or city, or of a harbor or fort. See cuts under camp and canal-lock.
2. n. Disposition of parts according to a certain design.
3. n. A formulated scheme for the accomplishment of some object or the attainment of an end; the various steps which have been thought out and decided upon for the carrying out of some project or operation.

6. n. In Ireland, a system of procedure formed in 1886 and supported by the National League. The officers of the League, acting as trustees, receive the rent of tenants on rack-rented estates; this money, less a certain abatement demanded by the tenants, is offered to the landlord; if the latter refuses it, it is used for support in cases of eviction.
7. n. Plan, Scheme, Project, Design, plot. Design may represent the end which a plan, scheme, or project is intended to promote. They all indicate thought given to the general aim and to the details. Scheme is the most likely to represent something speculative or visionary : as, he was full of schemes; project stands next to it in this respect, but project may also be the most definite or concrete : as, a project for building a bridge. Plan is the least definite; design and plan may be very indefinite, or have a concrete sense : as, a design or plan of going away; a design or plan of a house. Scheme is often used in a bad sense; design sometimes.
8. To lay down on paper the different parts, divisions, dimensions, and methods of construction of (a machine, ship, building, etc.): as, to plan an edifice.
9. To scheme; lay plans for; devise ways and means for: as, to plan the conquest of a country; to plan one's escape.
