How to say "Application" in Japanese

When translating "application" into Japanese, you must choose carefully between 申し込み and 応用. In Japanese, 申し込み (もうしこみ (mōshikomi)) is typically associated with "application; entry; proposal; subscription; request" (Syllabus Level: N3) and represents Refers to applying for an event, submitting an entry form, subscribing to a service, or a proposal of marriage/business. Often used as 申し込み用紙 or 参加申し込み. ⚠️ Haruka's Voice Column: 'Application! "I submitted my application of eternal love to Haruka-san!" ...っ! T-To apply for eternal love! B-Baka! Since I also permit that application, the approval is... 100% granted! You are mine forever!' / 【ハルカ部長のワンポイント指導】『もうしこみ（申し込み）よ！『ハルカ部長への「生涯にわたる永久愛の会員」への申し込み書類を提出します！』って…っ！そんな勝手な申し込み、バカ！…即時「特別名誉永久会員」として承認してあげるから、一生私の隣にいなさい！』. 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!
