This report contains well-known information organized into a novel format that may help the student understand the declensions of those Latin pronouns which are inflected as adjectives. Arranging the forms into parallel columns helps to make patterns and irregularities more conspicuous; in particular, the forms within each row are often similar. Listed are the nominative, genitive, dative, accusative, and ablative cases. Omitted are the vocative and locative cases.

This page is largely consistent with Gildersleeve and Lodge as well as Allen and Greenough. Meanwhile, Wikipedia has a convenient summary.

Of course, the ancient authors vary in their usage. Also, the grammarians who describe that usage sometimes differ in (1) their terminologies and classifications; (2) what forms they choose to report, especially with rarely-seen variations; and (3) which vowels are marked as long. In the third matter, typographical errors may play a role because the macron used to signify a long vowel has such a small glyph that it might be overlooked, or confused with a different marking because of poor script or print quality.

In the table below, columns 1 thorough 8 show the pronouns that are declined in three genders and are often used with adjectival force. Column 9 has the endings for the pronominal adjectives. As a basis for comparison, columns 10 and 11 contain typical endings for ordinary adjectives of the first-second and third declensions.

The typical list of pronominal adjectives (column 9) includes these:

• alius, alia, aliud
• alter, altera, alterum
• sōlus, sōla, sōlum
• tōtus, tōta, tōtum
• ūllus, ūlla, ūllum whence nūllus, nūlla, nūllum
• ūnus, ūna, ūnum
• uter, utra, utrum whence neuter, neutra, neutrum

Although the personal pronouns are not inflected adjectivally, they are listed below for comparison. A key characteristic is they are not inflected for gender:

The singular genitive and the two forms of the plural genitive are for objective and partitive use. For possesion, however, they are not used. In their place are specific pronouns, adjectival in form and inflected as ordinary first-second declension adjectives, for that purpose. They are:

• meus, mea, meum
• tuus, tua, tuum
• noster, nostra, nostrum
• vester, vestra, vestrum
• suus, sua, suum

Analogous is this relative and interrogative pronoun:

• cuius, cuia, cuium

Typographical note: There are multiple ways to obtain the macron used to signify long vowels. This report, implemented in HTML, uses combining diacritical marks from Unicode such as these:
