WSDL stands for Web Services Description Language . Its still in draft ver1.1 ( http://www.w3.org/TR/wsdl ). In simple terms WSDL describes what that the service interface and implementations are . Once you have built a webservice , there should be a way in telling the world what that service is all about and how to access it and what it returns etc ., WSDL primarily does that .
Now that would mean you will have loads of service descriptions around , how would you choose the one that is right for you ? - The answer lies in UDDI , which in turn enables classification and discovery of these services .
Almost forgot to mention this link which explains WSDL better than what i try to do in 4 lines ! http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dn_voices_webservice/html/service07182001.asp

WSDL stands for Web Service Definition Language.
"WSDL is a CONTRAC between server and client"
In order to successfully call a Web service you will need to know how to get to the service, what operations the service supports, what parameters the service expects, and what the service returns. WSDL provides all of this information in an XML document that can be read or machine-processed.
