Muodollinen is a Finnish adjective meaning formal, relating to form, structure, or established rules. It derives from muoto, form, and the suffix -llinen, which indicates that something has the quality of or is characterized by forms. The term is used across different domains to contrast with warmer, informal, or spontaneous practices.

In scientific and academic usage, muodollinen is common in phrases like muodolinen kieli or muodollinen logiikka. Muodollinen kieli refers to a formal language defined by precise syntactic rules and a specified alphabet, as studied in formal linguistics and computer science. Muodollinen logiikka and muodolliset todistukset describe formal systems of reasoning where inference rules are explicitly stated and proofs are carried out within a fixed framework. These concepts emphasize rigor, reproducibility, and unambiguous interpretation.

In social and cultural contexts, muodollinen describes etiquette, attire, and procedures that follow established conventions. Examples include muodollinen asu (formal dress), muodolliset tilaisuudet (formal events), and noudatettavat muodollisuudet (formalities). In this sense, the term signals compliance with predefined norms rather than spontaneity or ease.

Muodollinen is often contrasted with erilainen tai epämuodollinen, which denote informal or relaxed approaches. While it can imply rigidity, in many contexts muodollisuus also signals professionalism, clarity, and systematic organization. The exact nuance depends on context, ranging from technical formality in science to ceremonial formality in social life.
