This particular acrosstic was created on purpose. The plural of it already existed, but the singular of this is referenced on numerous other pages, so I wanted it to actually have those references point to a separate page to describe the rules of my acrosstics, which are slightly different than normal acrosstics.
Most distinct difference is the fact that each of the letters of the vertical word must always be the first letter of the horizontal word. Not the second, third, or seventh, always the first. Also, there are a few things that can make it easier to complete the acrosstic: an X can be used as the first letter in for instance the word eXperience, in which case the E is simply discarded.
Last freedom is the use of small additions: any horizontal word may be followed by for instance 2, 4, & or propositions like in or on. As long as the total acrosstic is a single flowing sentence all this is OK.
