The RED WORDS (also underlined) above have logical content, revealing the stucture of a set, or its relationship to another set. These RED WORDS have many synonyms in English, and the words are not always used with logical content. Thus, in [2] above, the word "and" occurs twice; the first "and" has little logical content, merely noting two sets; the second "and" has logical content, linking two properties (or qualities) of points in A B.
