Superlative adjectives in Slovenian grammar are used to express the highest degree of a quality. They are formed by adding the suffix „-ji‟ or „-naj‟ to the stem. The stem is the first part of the adjective without the „-en‟ ending. For example, the superlative form of „velik‟ (big) is „najveliki‟ (the biggest). It’s important to note that in Slovenian, the superlative always includes the definite article, producing a translation equivalent to „the most/biggest‟ in English.
