The Nuance Difference: "います" vs "申し込む"

In Japanese, both います and 申し込む are often translated to English but have distinct usages. います (います (imasu)) represents "to be, to exist (animate objects)" (Level: N5) and typically represents Polite form of いる. Used for the existence of animate objects. On the other hand, 申し込む (もうしこむ (mōshikomu)) translates to "to apply for, to make a reservation, to subscribe" (Level: N4) and is used for イベント参加やサービス利用など、何かを正式に願い出ること。他動詞。/ To formally request something, such as participating in an event or using a service. Transitive verb.. Mixing these up can sound unnatural to native Japanese speakers!
