決心します（けっしんします、keっshinしmasu）
- to determine

The Japanese word 決心します （けっしんします - *kesshin shimasu*） means "to make a decision," "to resolve," or "to determine." It signifies a firm commitment to do something, often after careful consideration or deliberation. It implies a strong intention and a readiness to act. It's more than just a passing thought; it's a decision that one intends to follow through on. It can also imply a resolve to overcome challenges or difficulties. The core meaning focuses on the act of deciding or resolving something, establishing a firm intention.

⚫︎将来、日本へ留学することを決心します。 Translation: I will decide to study abroad in Japan in the future. ⚫︎難しい問題ですが、頑張って解決する決心します。 Translation: It's a difficult problem, but I resolve to do my best to solve it. ⚫︎健康のために、毎日運動する決心します。 Translation: I will resolve to exercise every day for my health.

⚫︎決心します is a formal verb, so it's suitable for situations where polite language is expected, such as in business settings or when speaking to someone of higher status. ⚫︎It is typically used when you are making a conscious, firm decision about something, often involving effort or a long-term plan. ⚫︎You would use this when announcing your decision or commitment. For example, when you want to inform someone of your intention to do something. ⚫︎ It can be used to express an internal decision or to announce it to others.

⚫︎The word 決心します is written in hiragana as けっしんします. ⚫︎ The kanji form is 決心します. The kanji 決 means "to decide," "to determine," or "to fix," and 心 means "heart," "mind," or "spirit." The verb します (shimasu) is the polite form of "to do." ⚫︎Other forms of the verb include 決心する (kesshin suru - to decide), 決心した (kesshin shita - decided), and 決心しましょう (kesshin shimashou - let's decide).

⚫︎決める (kimeru): To decide (more general). ⚫︎決意する (ketsui suru): To resolve; to make up one's mind (similar meaning to 決心します but with a stronger sense of determination). ⚫︎断言する (dangensuru): To declare, to assert. ⚫︎意を決する (i o kessuru): To make up one's mind; to make a resolute decision (slightly more formal and literary).

⚫︎ There aren't direct antonyms because the opposite of making a decision would be to not make a decision or to be indecisive, which is not expressed as a single verb. ⚫︎However, words like 迷う (mayou - to hesitate, to be lost) or ためらう (tamerau - to hesitate, to waver) can describe states that are the opposite of making a decision.

試験に合格するために、毎日勉強する決心します。 ・Translation: I will decide to study every day to pass the exam. ・Explanation: This sentence expresses a firm decision to take action (studying) to achieve a goal (passing the exam).

困難に直面しても、諦めないで最後までやり抜く決心します。 ・Translation: Even if I face difficulties, I resolve not to give up and see it through to the end. ・Explanation: This sentence demonstrates a determination to persist despite challenges, indicating a strong resolution.

⚫︎The word 決心 itself is a compound word formed from the kanji 決 (ketsu), meaning "to decide," and 心 (shin), meaning "heart" or "mind." ⚫︎The verb します (shimasu) is simply the polite form of the verb "to do" (する - suru), adding formality to the phrase. ⚫︎Therefore, the etymology reflects the act of deciding in one's heart or mind.
