Swift Error: Variable used within its own initial value

When I'm initializing an instance of an entity I'm getting the error

Variable used within its own initial value

Here is the code throwing the error:

class func buildWordDefinition (word:String, language:Language, root:TBXMLElement) -> WordDefinition
let word = WordDefinition(word: word, language: language)

The error points at the

Here is the WordDefinition class:

class WordDefinition {
let word: String
let language: Language

init(word: String, language:Language)
self.word = word
self.language = language

What does this error mean ?

You are declaring a constant named word, and trying to use the argument with the same name to initialize it. The compiler tries to use the just declared constant to assign its own initial value, instead of using the argument.
