Dexter, dextĕră or dextră, dextĕrum or dextrum on the right hand, varies.

| Abl. | ūn-o | ūn-ā | ūn-ō |
In the Plural (required for Nouns with a Plural form but a Singular meaning) it is declined like bŏnŭs.
The following Pronominal Adjectives also have -īŭs (or -ĭŭs, see § 448*) in G. Sing., and -ī in D. Sing. of all Genders.
| ūllus any | sōlus only |
