==== {{anchor|d2r}} Second-declension ''-r'' nouns ====
Some masculine nouns of the second declension end in ''-er'' or ''-ir'' in the nominative singular. The declension of these nouns is identical to that of the regular second declension, except for the lack of suffix in the nominative and vocative singular.

Some (but not all) nouns in ''-er'' drop the ''e'' in the genitive and other cases. For example, {{wikt-lang|la|socer|socer, socerī}} ('father-in-law') keeps its ''e''. However, the noun {{wikt-lang|la|magister|magister, magistrī}} ('(school)master') drops its ''e'' in the genitive singular.

For declension tables of second-declension nouns, see the [[Wiktionary:Appendix:Latin second declension|corresponding Wiktionary appendix]].
