We've had some interesting discussions of Part of Speech on this list, and, while we don't all agree as to which ones and how many English grammar needs, there is broad agreement that they are defined on morphological and syntactic grounds, as well as semantic. School grammars tend to offer much more notional classification reflecting the eight pars orationis of the Greco-Latin grammatical tradition. I've used the "possessive pronoun" terminology consistently throughout my career, both as a linguist and as a grammar teacher. The words simply do not belong to the same lexical class (part of speech). English adjectives may take the suffixes -er and -est, are preceded by number words and determiners (articles, demonstratives, possessive pronouns), and may also be predicative without changing form. Possessive pronouns, on the other hand, precede number words and adjectives, are uninflectable except in that they are the diachronic product of inflecting a pronoun root, and may change form to be predicative (mine, (thine,) hers, ours, yours, theirs). "His" and "its" don't show this inflection. And, of course, pronouns a closed class of function words while adjectives are an open class of content words. The standard reference grammars listed below pretty much agree on this treatment. I've used the Greenbaum as a text a number of times. School grammars tend to be more influenced by grammatical traditions. Some standard reference grammars: Biber, Douglas; Stig Johansson, Geoffrey Leech, Susan Conrad, and Edward Finegan. 1999. Longman Grammar of Spoken and Written English. London: Pearson ESL. Greenbaum, Sidney. 1996. The Oxford English grammar. New York: Oxford University Press. Huddleston, Rodney D., and Geoffrey K. Pullum. 2002. The Cambridge Grammar of the English Language. London: Cambridge University Press. Quirk, Randolph; Sidney Greenbaum, Geoffrey Leech, and Jan Svartvik. 1985A Comprehensive Grammar of the English Language. London: Longman. For historical purposes, I go to Jespersen's seven volume A Modern English Grammar on Historical Principles, but modern reference grammars agree quite extensively with his grammatical analyses. In short, I agree with Swan. Herb This may sound elementary but is anyone using a reference grammar which classifies 'my', 'your', 'her' etc. as 'possessive pronouns' and not as 'possessive adjectives'?. For example, Thomson and Martinet (A Practical English Grammar - page 75) classifies them as possessive adjectives. On the other hand, Michael Swan's Practical English Usage (p. 416) classifies them as possessive pronouns and states 'They are not adjectives though they are sometimes called 'possessive adjectives' in older grammars and dictionaries'. Is there anyone on the List who follows Swan's classification?
