緊張
「緊」は緊密の意、「張」は張るの意から成る。
「緊張」 (kintō) describes a multifaceted state of being stretched or tightly wound, encompassing both mental and physical aspects. It translates to various English words depending on context, such as tension (a state of mental or emotional strain), nervousness (a feeling of worry, anxiety, or unease, often before an event), stress (mental or emotional strain or tension resulting from adverse or demanding circumstances), strain (a feeling of stress or pressure, or a physical stretching), and anxiety (a feeling of worry, nervousness, or unease about something with an uncertain outcome). Unlike English, which often uses specific words to differentiate these nuanced feelings, "緊張" broadly covers the feeling of being on edge, highly focused, or under pressure, whether it's due to an important performance, a challenging situation, or simply a taut atmosphere. It can manifest physically (e.g., stiff muscles, rapid heartbeat) or mentally (e.g., heightened alertness, apprehension).
