nonstandardrare

Nonstandardrare is a term used in linguistics and computational lexicography to categorize lexical items that are both nonstandard in form and rare in usage within large reference corpora. Such items often originate in creative spelling, deliberate orthographic variation, niche jargon, or idiolectal innovation, and they tend to be infrequent in general-language datasets while persisting in specific communities, genres, or domains.

Definition and boundaries: The term describes a combination of two properties: nonstandardness, meaning the form deviates from standard orthography or phonology, and rarity, meaning the item occurs with low frequency. This combination distinguishes nonstandardrare from words that are nonstandard but common (slang in certain registers) or rare but standard (archaisms).

Identification and usage: Researchers identify nonstandardrare through corpus analysis, applying frequency thresholds and examining orthographic variants. They may also track stability over time and across communities. In natural language processing, handling nonstandardrare poses challenges for tokenization, normalization, and language modeling; strategies include maintaining a supplemental lexicon, employing subword models, or normalizing forms while preserving original data for sociolinguistic analysis.

Applications and examples: The concept is used in lexicography, sociolinguistics, and NLP to study social and linguistic factors behind rare nonstandard forms. Illustrative examples include invented coinages or modified spellings that appear in limited communities or in creative writing, such as snizzle in a fan forum or quibbit in a niche online zine. The term remains informal and its usage varies across disciplines; it serves as a descriptive heuristic for data annotation and model development.
