We skip familiar definitions known by a majority of English speakers. For example, since we consider the words meet, souse, and sleeper elementary vocabulary, books using these words only in the everyday sense are skipped:

• skipped:
  Bob failed to meet us because he is a heavy sleeper when he is soused.
• included:
  It would be meeter for Bob to eat souse on sleepers when trains are not coming.

Rather than making our job easier, this is a major hurdle in completing the vocabulary collections; we must verify not only whether the word is used in the book, but also what sense it is used. The confounded words are the bane of this site's existence.
