Is there any difference in meaning between "Holy Spirit" and "Holy Ghost"? Is there any difference in meaning between Holy Spirit and Holy Ghost?

When should we use Holy Spirit and Holy Ghost?

By the way, Wikipedia says:


  Holy Spirit, or Holy Ghost, is a term found in English translations of the Bible, but understood differently among the Abrahamic religions


I already asked about the English meaning. But what are the differences in religious meanings?
Holy Ghost is from the KJV, Holy Spirit is more modern.  

It's actually a little more complicated than that. In the New Testament, the KJV uses the term Holy Ghost 89 times, and the term Holy Spirit 4 times. So it actually uses both. But modern translations use Holy Spirit exclusively.

The wikipedia article is not saying that Holy Ghost and Holy Spirit are understood differently.  Its trying to say that Judaism, Christianity, and Islam view the Holy Spirit differently.

Nonetheless, some people might argue that Holy Ghost gives a more personal character to the Holy Spirit than Holy Spirit, assuming that Ghost sounds more like a person than Spirit.  But that's probably a pretty iffy argument.
