The "purity" does not exist in languages. What do you define by purity? What do you mean by purity? When do you consider that a language is a language? What do you mean when you say that irish gaelic is pure? Do you mean there has never been any influences form the picts (scottish) or the welsh?
That question is simply a non sense.
there is not purity in any language (dead or not) since there have alaways been some exchanges.
