the meaning of a phrase
The passage below comes from the following website.
Can you tell me the meaning of the underlined “touching or otherwise”?
I cannot figure what it refers to even though I tried hard.
http://awaisaftab.blogspot.kr/2012/05/semantic-version-of-russells-paradox.html Here goes: There are two kinds of words, those that refer to themselves (autological) and those that don’t (heterological). Some examples of autological words are “short” (which is a short word), “polysyllabic” (which has several syllables), and our favorite, “seventeen-lettered” (which has seventeen letters). Examples of heterological words are “knockkneed” (a word that has no knees,
touching or otherwise) and “monosyllabic” (a word that has more than one syllable).
