In the sense you are meeting here, nerveless describes someone’s fingers (or sometimes hands) when they cannot hold a thing firmly. After a shock — bad news, a near miss, a sudden fright — the hands can go slack, as if the strength has run out of them.

In the sense you are meeting here在這裡遇到的意思, nerveless describes someone's fingers nerveless是在形容某人的手指 (or sometimes hands)有時是手 when they cannot hold a thing firmly拿不穩東西的時候. After a shock經歷驚嚇之後 — bad news壞消息、 a near miss千鈞一髮、 a sudden fright突如其來的驚嚇 — the hands can go slack手可能會變得無力, as if the strength has run out of them彷彿力氣都被抽走了.

A glass slips. A pen drops. We say the fingers were nerveless. “Nerve” here is not “worry”; it is the living strength and feeling in the body. Take that away, and the grip goes.

A glass slips杯子滑落. A pen drops筆掉了. We say大家會說 the fingers were nerveless手指nerveless了. Nerve here這裡的nerve不是 is not worry擔心的意思; it is the living strength and feeling in the body而是身體裡活生生的力量和知覺. Take that away把那拿走, and the grip goes握力就沒了.

Though actually this is not the only way English uses the word, and the other way can look like the opposite. In sport, and in stories about brave people, nerveless often means “not nervous at all”: a nerveless penalty kick, someone whose hands do not shake when it matters. Same pieces, two pictures: no strength in the fingers, or no fear in the heart.

Though actually不過其實 this is not the only way英語不是只有這一種用法 English uses the word, and the other way而另一種用法 can look like the opposite看起來像是相反的意思. In sport在運動裡, and in stories about brave people或描寫勇敢人物的故事裡, nerveless often means not nervous at allnerveless常常是一點都不緊張的意思: a nerveless penalty kick沉著冷靜的一記罰球, someone whose hands do not shake when it matters或關鍵時刻手不會抖的人. Same pieces, two pictures同樣的字、兩種畫面: no strength in the fingers手指沒力氣, or no fear in the heart或心裡沒有恐懼.

You tell them apart from the rest of the sentence. The “slack after a shock” meaning is a little more like story-language; the “calm under pressure” meaning is the one you will hear when people talk about sport. There is also an older use, “without courage,” but you can live without that one for now.

Same pieces, two pictures同樣的字、兩種畫面: no strength in the fingers手指沒力氣, or no fear in the heart或心裡沒有恐懼. You tell them apart你要從 from the rest of the sentence句子的其他部分去分辨. The slack after a shock meaning「驚嚇後手軟」這個意思 is a little more like story-language比較像故事語言; the calm under pressure meaning「沉著冷靜」這個意思 is the one you will hear才是你會 when people talk about sport聽到人們談運動時用的. There is also an older use還有一個較舊的用法, without courage「沒有勇氣」, but you can live without that one for now但你現在可以先不管它.
