Overview
SIST-TP ISO/TR 20694:2018 - A typology of language registers is a Technical Report from ISO/TC 37 that establishes general principles, definitions and examples for language registers in both descriptive and prescriptive settings. It clarifies ambiguous uses of the term register, proposes a multi-faceted typology (spoken/written/modalities), and provides guidelines for documenting and using registers across many languages. The report supports consistent treatment of registers in standards work and in computational language resources.
Key topics and technical coverage
- Definitions and scope: precise definitions of terms such as language variety, register, formal/informal (high/low) registers, technical register, neutral register, slang, in-house register, subregister, etc.
- General principles: how registers vary by situation, formality, modality and social context; descriptive vs. prescriptive registers; continuums and subregistries.
- Markers of registers:
- Lexical markers (domain-specific vocabulary, archaic forms, contractions, slang, foreign words).
- Phonological markers for spoken registers.
- Grammatical features (morphology, tense/use of passive, sentence length, nominal complexity, conjunctions).
- Honorifics and forms of address (politeness systems, vocabulary and grammar in honorific registers).
- Mapping and translation: register equivalence across languages, conveying register in translation, inconsistencies and potential loss of register information, and implications for translation memories.
- Registers and diglossia: interactions between register variation and diglossic situations.
- Relationship with other ISO standards (e.g., ISO 24620-1, ISO 639) for metadata and language coding.
Practical applications
SIST-TP ISO/TR 20694:2018 is directly useful for:
- Terminology and standards development - selecting appropriate register for normative text and terminology.
- Translation and localization - matching target-language register to source register; improving translation memory tagging.
- Lexicography - describing non-geographic language variants and register labels in dictionaries.
- Second-language teaching - informing curricula so learners can choose appropriate register and avoid pragmatic errors.
- Software and NLP - tagging language variants, improving language-resource metadata, and designing user-facing content (UI text, help, chatbots).
- Communications and public health - selecting neutral or simplified language registers for clear messaging.
Who should use this standard
Terminologists, translators, lexicographers, language engineers, localization managers, standards writers, curriculum designers, corpus linguists and NLP developers will find ISO/TR 20694 valuable for consistent, interoperable handling of language registers, register mapping and metadata for language resources.
