Yes, there are several definitions for perspective.

Here are some from the American Heritage Dictionary of the English Lanuage,
Third Edition:

per·spec·tive (p?r-spek'tiv) noun


1. The technique of representing three-dimensional objects and depth
relationships on a two-dimensional surface.

2. a. A view or vista. b. A mental view or outlook: "It is useful
occasionally to look at the past to gain a perspective on the present"
(Fabian Linden).

3. The appearance of objects in depth as perceived by normal binocular
vision.

4. a. The relationship of aspects of a subject to each other and to a whole:
a perspective of history; a need to view the problem in the proper
perspective. b. Subjective evaluation of relative significance; a point of
view: the perspective of the displaced homemaker. c. The ability to perceive
things in their actual interrelations or comparative importance: tried to
keep my perspective throughout the crisis.



These are ordinary, everyday definitions in Standard English., which
everyone can easily understand. Note that there is NOTHING in them--any of
them--which declares that distance alone must be the determinant of
perspective.

Numbers one, three, and four describe an aspect of photographs that is
determined by camera position relative to the subject and is *not*
influenced by lens focal length. Number two is a general term, not a
specific technical term.

None of those definitions says that in photography it's only
influenced by camera position, no. So what? That's a general
dictionary definition, not an art text or a photography text or an
optics text.
