What does "genki desu" mean in Japanese?


I know it is used to respond to someone or something, but i don't get the
meaning of it?




The expression 元気{げんき}です can for instance be the answer in:

> —How are you?
>
> —I’m fine.

The word _genki_ (元気 or げんき) means that you are full of energy (vigour),
healthy, in a good mood et cetera. It may also be used in other situations.
Note that there is an element of healthiness, wellbeing or alertness involved
in this expression.
