Try this:

([A-Za-z])+( [A-Za-z]+)*
                       ^^ here

* means to repeat the group zero or more times. If you need it to be one or more times, then use +. Another thing you can use [ ]+ instead of space to handle one or more consecutive spaces.

Also, if you need, you can use anchor ^ and $ around your regex. Like ^...regex...$

You can do it as:

^([\sA-Za-z]+)$
