Plain and Plane :



Both of these words have to do with flatness. A flat prairie is a plain, and you use a plane to smooth flat a piece of wood.


“Plain” is also an adjective which can describe things that are ordinary, simple, or unattractive.


But whether you go the airport to catch a plane or meditate to achieve a higher plane of consciousness, the meanings that have to do with things high up are spelled “plane.”
