How to say "Application" in Japanese

When translating "application" into Japanese, you must choose carefully between 適用 and 応用. In Japanese, 適用 (てきよう (tekiyou)) is typically associated with "application (of a rule, law, principle, etc.)" (Syllabus Level: N3) and represents The act of putting a rule, law, condition, or principle into operation or use. Often used in formal contexts regarding regulations or policies.. On the other hand, 応用 (おうよう (ōyō)) maps to "application; put to practical use; apply" (Syllabus Level: N3) and represents Refers to applying knowledge, skills, or theories to practical situations or for practical purposes. It implies using something in a new or different context to solve a problem or create something new. 「知識や技術を具体的な状況で使うこと。学んだことを実際の場面で活かすという意味合いがあります。」. A literal translation of "application" can often sound unnatural to native Japanese speakers if mixed up!
