How to say "Establishment" in Japanese

When translating "establishment" into Japanese, you must choose carefully between 定着 and 樹立. In Japanese, 定着 (ていちゃく (teichaku)) is typically associated with "establishment, rooting, becoming fixed" (Syllabus Level: N2) and represents Used when something new becomes firmly established or widely accepted, like a custom, a system, or knowledge. 新しい物事や習慣、知識などがしっかりと根付き、一般に受け入れられること。. On the other hand, 樹立 (じゅりつ (juritsu)) maps to "establishment, founding, setting (a record)" (Syllabus Level: N2) and represents Used for establishing something significant, such as a new government, a record, an organization, or a system. It implies creating or setting something for the first time or to a new, often high, standard.. A literal translation of "establishment" can often sound unnatural to native Japanese speakers if mixed up!
