Something shaky is trembling — or just feels like it. When we're not confident, we feel shaky.
Being shaky is something that happens to us all. The first day of a job or class can make anyone feel shaky — even the teacher or boss. When you get extremely nervous, your hands might literally shake. That's not fun, but it might help you remember what shaky means. A building in an earthquake and a tree in the wind can also be shaky. One person we hope is not shaky — in either way — is a surgeon.
