Tyyliohje

Tyyliohje, often translated as a style guide, is a document that defines preferred language, writing style, and formatting for a publication, organization, or project. Its aim is to ensure consistency across texts and media.

A Tyyliohje covers linguistic rules such as orthography, punctuation, capitalization, hyphenation, abbreviations, and the handling of numbers, dates, times, and currencies. It also specifies typography choices, including font usage, line lengths, headings, emphasis, and spacing, as well as formatting conventions for citations, references, lists, and quotations. In addition, it describes tone, voice, and register to align content with branding and audience expectations.

Many Tyyliohje include guidelines for accessibility and inclusivity, localization for different languages or regions, and practical templates, examples, and checklists. They often define an editorial workflow, including review, approvals, and version control, so updates are managed consistently.

Creation and governance: Tyyliohje are typically developed by communications or editorial teams, sometimes with linguistic or design specialists. They evolve over time to reflect changes in language use, technology, and organizational needs, and may be published publicly or kept internal.

Relationship to other standards: Organizations may base their Tyyliohje on established external style guides and industry terminology, adapting them to Finnish language conventions and product or platform requirements.
