To act tremulously means to do something with shaking or quivering, often due to fear or nervousness. Imagine holding a fragile glass during an earthquakeβthat's acting tremulously. It conveys a sense of vulnerability and lack of control. It's different from being brave or confident; think more along the lines of anticipation before a big performance or facing a scary situation. It's like your body is expressing uncertainty. It's the opposite of acting boldly.
