Talk:Subject pronoun

Is the list complete?
Question: e.g.: It is a cat. In the sentence above, does "it" refer to the word "cat" of the language or the concrete animal of the real world? I can't see why each wouldn't also be a subjective pronoun.
 * Then each at once his falchion drew,
 * Each on the ground his scabbard threw,
 * Each looked to sun, and stream, and plain
 * As what they ne'er might see again! — Walter Scott, The Lady of the Lake, 1810

"Subject" more frequent than "subjective"
The terms "object pronoun" and "subject pronoun" (without the "-ive" suffix) can be considered standard, based on the objective (!) criterion of their vastly greater relative frequencies. See the graph at Google Ngram Viewer. Please, someone who knows how, edit the title of this article. Kotabatubara (talk) 23:22, 13 February 2012 (UTC)

what/who
Why are "what" and "who" included but not e.g. "this", "that", "these", "those"? Ehrenkater (talk) 17:15, 23 February 2015 (UTC)
