Is there any difference between *Holy Spirit* and *Holy Ghost* meaning?

When should we use *Holy Spirit* and *Holy Ghost*?

BTW, [Wikipedia][1] 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](http://english.stackexchange.com/q/159571/61081) abut the Enlish meaning. But what are the differences in religious meanings?
