Contributing to the confusion? Imagine how hard it would be for US to learn Vietnamese...

If 'interdependent' is a word, so must be 'intradependent'.

[Silver Rusher]

Actually, GoreBag, I thought the same a while ago until I was unable to find any dictionary entry on it.

[L'Impresario]

The term exists, but it's not quite approved, more of a neologism. If there's a specific niché to be filled, the word could gain some ground, probably with some intellectual backing, I gather it'll be a social scientist that's more likely to use it in a specific context (excluding economists; they tend to be rather unimaginative with such things). In the meantime other expressions are used till it becomes vogue amongst generic Sub-saharan environmental policy strategists.

autarky sounds like exactly the idea of what i was looking for. Introdependent is probably not used because everything depends on workings from within. This dependency says nothing about the autarky of a country.

a watch company may be dependent on its company watch makers. this does not mean it is entirely dependent. Autarky means entirely dependent
