Instead of Wikipedia, why not try a dictionary? Looking up monoid using

  An operator * and a value x form a monoid if * is
  associative and x is its left and right identity.

On the other hand, appendable doesn't seem to be a word, and while you
can infer that it means "something that can be appended to", that's only
half of the story...
