Tyylioppaita

Tyylioppaita is Finnish for a style guide or style manual, a document that collects rules and conventions for writing and presenting texts. It is used to ensure consistency across authors and materials and can be produced by publishers, organizations, universities, or governmental bodies.

A typical tyyliopas covers orthography, punctuation, capitalization, hyphenation, numerals, dates, and measurement units. It also prescribes terminology, tone, voice, and readability guidelines, as well as formatting and layout rules for typography, headings, lists, quotations, and citations. In addition, it often includes rules for abbreviations, foreign words, and translations, along with examples of correct usage. Many tyylioppaita also specify citation styles (for example APA, MLA, or Chicago) and reference management practices, though individual institutions may adapt these to their own house style.

In Finland, style guides may be issued by publishers, media outlets, universities, and government bodies, and there are widely used reference resources such as Kielitoimiston ohjepankki that inform orthography and usage. The purpose is to promote clarity, consistency, accessibility, and brand or institutional identity. Tyylioppaita have evolved with digital media, accommodating online content, metadata, accessibility considerations, and search-friendly formatting. While forms vary, the core aim remains the same: to provide a shared framework that helps writers produce coherent and professional texts across contexts.
