nervousness

Nervousness is that feeling when you get anxious or worried about something. It's like having butterflies in your stomach.

When people talk about nervousness, they usually mean it in relation to a specific situation or event. For example, someone might say "I'm really nervous before my job interview" or "I was so nervous on my first day of school." In these cases, nervousness is often used to describe the feeling of being uneasy or on edge because you're not sure what's going to happen next.
