Here’s an example of Normals mis-hearing and mis-interpreting spoken terms that is particularly humorous to me: “two-trek road.” An amusing lack of thought went into that mis-interpretation, since a “two-track road” is definitive: the two TRACKS are made by wheels on axeled vehicles wearing a path, in much the same way that game trails are made (though game trails are almost always “one-track” trails, of course). “Two-trek” seems to indicate to me that the person who has written the term in this way has never even seen a two-track road, or if he has, has any understanding of how such a thing is made by the TRACKS of two wheels (and more, repeated by another one or two axles).
Understanding what one hears requires thought much more frequently than most Normals seem to be aware of.
