Is there commonly accepted opinion on what lexemes this/that are, determiners or pronouns?

E.g. in the following phrase:

... can help you work these out

these seem to show some properties of pronouns more than that of determiners.

More generic question: is there commonly accepted classification of the English closed class lexemes?

    Why can't it be both? (i.e. the same word can play different grammatical roles in different sentences) Jun 27 '18 at 7:54

    An answer about the Penn Treebank POS set is hardly an answer to the classification of this and that. And the other question is a good one, too. Is there a decent classification of closed class lexemes?

  • "This/that" and the plural forms "these/those" belong to the category "demonstrative determinative", where they typically function as determiner, e.g. "this guy", "these houses". But they can also function in 'fused determiner-head constructions, which is the case in your example. In the 'fused determiner-head' construction, the head and the determiner are combined or fused into a single word -- in your example "these", where we understand "these x", where "x" is interpreted from the discourse.

    Members of the closed class comprise: preposition, determinative, subordinator and coordinator. These categories do not readily accept the addition of new members.
