Basque is an ergative language. In contrast, all IE languages are nominative languges. Georgian, as best I understand, is also a nominative language, but has an auxiliary ergative structure apparently used for emphatic forms. Basque and Georgian are often mentioned together because of this.
I'm told you need to learn some Basque before you can really appreciate the distinction between ergative and nominative languages.
The usual contrast between nominative and accusative, and how the verb connects the two, as well as how the verb relates to what we term 'passivity' and 'transitivity', is quite different in an ergative language.
In short, the noun in the subject position of a sentence in ergative languages inflects differently, depending on if the verb is transitive or not.
