I use this regex "\w{3}\-\w{2}" but return "est-te". What's wrong?
You want to get 2 disjoined parts in a string. You need to match each parts and then join them.
This RegEx: "(\w{3}).*(\-\w{2})" will match each part, you just have to join them.
Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[

Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[

Expresso Regular Expression Tool[

RegExr: Learn, Build, & Test RegEx[

This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:
