Can the term 'possessive pronouns' be used as a general term for both possessive pronouns and possessive adjectives?
At the university I was taught that there are two kinds of possessive pronouns: possessive pronouns adjectives and possessive pronouns nouns. In most today's textbooks they are called possessive adjectives (e.g. my, his, their) and possessive pronouns (e.g. mine, his, theirs) respectively. (I was also taught that a possessive pronoun is an 'absolute' form of a possessive adjective.)
Update: ("Possessive determiner" – Wikipedia)
The words my, your, etc. are sometimes classified, along with mine, yours etc., as possessive pronouns or genitive pronouns, since they are the possessive (or genitive) forms of the ordinary personal pronouns I, you etc. However, unlike most other pronouns, they do not behave grammatically as stand-alone nouns, but instead qualify another noun – as in my book (contrasted with that's mine, for example, where mine substitutes for a complete noun phrase such as my book). For this reason, other authors restrict the term "possessive pronoun" to the group of words mine, yours etc. that substitute directly for a noun or noun phrase.
Some authors who classify both sets of words as "possessive pronouns" or "genitive pronouns" apply the terms dependent/independent or weak/strong to refer, respectively, to my, your, etc. and mine, yours, etc. For example, under this scheme, my is termed a dependent possessive pronoun and mine an independent possessive pronoun.
