jukujikun

Jukujikun is a type of Japanese kanji compound where the characters are read according to their native Japanese or Chinese readings, rather than following the standard Sino-Japanese (on'yomi) or native Japanese (kun'yomi) pronunciations. Unlike other kanji compounds, jukujikun has a unique reading that does not directly correspond to the individual readings of each character, making it a form of irregular or non-standard reading.

This type of reading often emerges from historical, cultural, or contextual factors, particularly for words with specific meanings, names, or borrowings that do not align with typical phonetic patterns. Jukujikun are frequently used for place names, plant names, and personal names, where the reading is established by tradition or usage rather than linguistic rules.

An example of jukujikun is the word "森" (meaning "forest"), which is read as "mori" in Japanese, but can appear in compound forms with readings that deviate from the standard on'yomi or kun'yomi patterns. Another example is the word "山" (meaning "mountain"), which is read as "yama," but in certain compounds, it might adopt different readings based on historical conventions.

Since jukujikun does not follow standard phonetic or morphological patterns, it can pose challenges to learners of Japanese. Its irregularity underscores the complex history of kanji development and usage, reflecting a blend of linguistic, cultural, and historical influences that shape the Japanese writing system.

Overall, jukujikun exemplifies the richness and complexity of kanji readings, contributing to the depth of Japanese written language.
