蔓延る

• 読み: はびこる
• ローマ字: habikoru
• 漢字の分解: 蔓 (man/tsuru) — vine, tendril; 延 (en/no) — extend, spread
• 発音: /ha.bi.ko.ɾɯ/

意味

To spread unchecked; to flourish excessively; to run rampant; to be pervasive. Used for negative phenomena spreading beyond control.

A Group 1 (godan) verb typically used for harmful or unwanted phenomena spreading beyond control — weeds overgrowing, corruption spreading, harmful ideologies proliferating. The nuance carries a judgment that the spreading is excessive and should be checked but isn't. Unlike 広まる (to spread, neutral), 蔓延る implies something invasive and difficult to contain.
