I guess what I find confusing is, for example we look at the word "polyamory" and derive a ballpark definition from it based on its parts. "Poly-" means "many" and "-amory" means "love." Hence, polyamory -- many loves. This makes sense. The official definition takes a little tweaking, but the parts of the word have put us on the right track.
Why, then, do we look at the word "spirituality," and disregard the presence of "spirit" as part of it? The suffix "-uality" infers "of the prefix as a noun ..." "-al" means "of or pertaining to" (per
Wiktionary), "-ity" forms the noun referring to the state, property, or quality of conforming to the adjective's description (per
Wiktionary). Putting these parts together we get something on the order of, spirituality = the state of being of the spirit.
This isn't rocket science, you really don't need to look at Wiktionary to comprehend where the parts of the word are pointing. How can one be "of the spirit" if one does not believe in spirits? But hey, let's consult
Wiktionary. Definition One: "The quality or state of being spiritual." Definition Two: "Concern for that which is unseen and intangible, as opposed to physical or mundane." Definition Three: "Appreciation for religious values."
And what does "spiritual" mean? Consulting
Wiktionary ... One: "Of or pertaining to the spirit or the soul." Two: "Of or pertaining to God or a place of worship; sacred." Three: "Of or pertaining to spirits; supernatural." Four: "Consisting of spirit; not material; incorporeal." Five: "Of or relating to the intellectual and higher endowments of the mind; mental; intellectual." Six: "Controlled and inspired by the Holy Spirit; pure; holy." Seven: "Not lay or temporal; relating to sacred things; ecclesiastical."
Granted, Definition Five refers to the intellect. But come on, that's one definition out of seven. And it's only because the mind and the spirit tend to be thought of as synonymous. A word with the word "spirit" in it, strongly implies a world with spirits in it. I guess I've given it more thought, and I'm inclined to not describe myself as spiritual.
