Erityisin

Erityisin is a Finnish adjective form that functions as the superlative of eriyinen? No, of eriyinen. It expresses the utmost degree of the quality “special” or “particular,” roughly translating to “the most special” or “the most particular.” In usage, eriy… er, the form denotes that one item, person, or feature stands out above all others in a set.

In practice, erityisin appears in written Finnish and is most common in formal or literary style. It is the singular, nominative form; for other numbers or cases, the form changes according to standard Finnish inflection rules, and the corresponding plural superlative would be erityisimmät (the most special). The adverbial counterpart is erityisesti, which means “especially,” but it is not interchangeable with erityisin, which carries a stronger, comparative sense of absolute extremity.

Etymologically, erityisin is derived from the adjective eriyinen/erityinen, meaning distinct or special, with the Finnish superlative suffix -isin. The construction parallels other -in/-isin superlatives in Finnish and conveys emphasis rather than a mere comparison. The term is largely confined to contexts where a definite, highest degree of distinctiveness is being stated.

Related terms include eriyinen/erityinen (the base meaning “special” or “distinct”) and erityisesti (the adverb “especially”). While erityisesti is common in everyday language to introduce emphasis, erityisin remains a marked, formal option for signaling the peak degree of a quality.
