The mere idea of swimming across the river made me tremble.
She trembled with fear.
I tremble with fear at the thought of an injection.
He trembled at the thought of the earthquake.
She felt her knees tremble.
The leaves trembled in the wind.
I felt my hands tremble.
Immediately I saw him, I trembled with fear.
There was a tremble in her voice.
I may seem confident, but I get extremely nervous speaking in front of people. My hands tremble, I get all tongue-tied, and sometimes I don't even know what I'm saying myself.
Immediately she heard his voice, she trembled with fear.
