Editing Latin declension (section)

==== Comparatives and superlatives of ''-eus/-ius'' adjectives ====
First and second declension adjectives that end in ''-eus'' or ''-ius'' are unusual in that they do not form the comparative and superlative by taking endings at all. Instead, {{wikt-lang|la|magis}} ('more') and {{wikt-lang|la|maximē}} ('most'), the comparative and superlative degrees of {{wikt-lang|la|magnoperē}} ('much, greatly'), respectively, are used.

Many adjectives in ''-uus'', except those in ''-quus'' or ''-guus'', also follow this rule.
