From The Collaborative International Dictionary of English v.0.44 [gcide]:

Boundary \Bound"a*ry\, noun; pl. {Boundaries} [From {Bound} a limit; cf. LL. bonnarium piece of land with fixed limits.] That which indicates or fixes a limit or extent, or marks a bound, as of a territory; a bounding or separating line; a real or imaginary limit.

But still his native country lies Beyond the boundaries of the skies. --N. Cotton.

Sensation and reflection are the boundaries of our thoughts. --Locke.

Syn: Limit; bound; border; term; termination; barrier; verge; confines; precinct.

Usage: {Bound}, {Boundary}. Boundary, in its original and strictest sense, is a visible object or mark indicating a limit. Bound is the limit itself. But in ordinary usage the two words are made interchangeable.
