- 1坐立難安的、緊張兮兮的（表現在動作上的那種不安）
Twitchy describes someone who is nervous in a way you can see in their body — they cannot sit still, their eyes keep moving to the door, their fingers tap. It is not deep fear and not a calm worry; it is , restless, on edge, as if something is about to happen. You feel twitchy before a test, or when you are waiting for news, or when you are in a place that does not feel safe. It is informal and a bit physical, which is why it sounds more alive than 'nervous'. It also gets used for groups and even for markets and governments: 'investors are twitchy', 'the police were twitchy that night' — meaning ready to react fast, maybe too fast. And it can describe a thing that moves in small sudden jerks: a twitchy muscle, a twitchy steering wheel that responds to the smallest touch. That last use is not about feelings at all.
組成twitch（抽動）+ -y（形容詞字尾，帶有那種性質）— literally 'full of small jerky movements'.
