Excuse me; as a newcomer, this is the first time I've seen this thread. I've read it prayerfully, and dismissed nothing out of hand; and, by the grace of God, I am always willing and eager to be edified and enlightened by my brethren.

But I must say, in all humility and charity, that this is gnat-straining at its most preposterous. The Holy Spirit is the Holy Ghost is the Spirit of Truth is the Comforter. The fact that there are different terms only demonstrates the creativity and versatility of the One Who gave the words by inspiration.

What is a "ghost?" Supposedly, the returned spirit of one who has died.

That's precisely what the Holy Spirit is: the Spirit of Christ.

Forgive me if I sound abrupt, but this is a tempest in a teapot.
