folk taxonomy
Anthropological term for traditional, culturally specific classification systems, often contrasted with scientific taxonomy.
Folk taxonomy refers to a classification system for plants and animals rooted in local culture.
民俗分類 is a near-synonym also used in anthropology, but 民間分類 emphasizes 'folk' or 'popular' classification, while 民俗分類 stresses 'ethnological' classification.
Compound of 民間 (folk, private sector) and 分類 (classification). The term is a modern academic coinage, likely a calque of English 'folk taxonomy'.
