根幹

• Reading: こんかん
• Romaji: konkan
• Kanji breakdown: 根 (kon/ne) — root; 幹 (kan/miki) — trunk, main stem
• Pronunciation: /ko.ŋ.ka.ɴ/

Meaning

Root and trunk; the fundamental basis or core of something.

A noun using the tree metaphor — roots (根) and trunk (幹) — to express the essential, central foundation of something. Stronger and more absolute than 基礎 (basis) or 根拠 (grounds); it implies that without this element the entire structure collapses. Very common in political, philosophical, and critical discourse.

Examples

1. 民主主義の根幹をなすのは、自由な言論と公正な選挙だ。 Free speech and fair elections form the very foundation of democracy.
2. 今回の不祥事は、会社経営の根幹を揺るがす問題となった。 This scandal has become a problem that shakes the very core of the company's management.
3. 教育制度改革は、社会の根幹に関わる慎重な議論が必要だ。 Education system reform requires careful deliberation, as it touches the fundamental basis of society.
