It is my personal belief that the words and the process of a spell does not make it real. It is the how. This is brought about by the practitioner.
While someone could just come on here and attempt the first spell they find; I do not feel that they will be able to accomplish much with first knowing how to utilize a spell, and second having experience in doing so.
For example, I could list a spell as such:
Four corners unite,
In the black where they bite,
In the white pure with taste,
Do flush clear with haste.
Without meaning it is useless.
I could say it is a cleaning spell for your toilet. And it suddenly has more context.
Still, it is fairly useless.
I could say burn Frankincense, toss a four clear quarts, one pink quarts, and the feather of a pigeon.
Still, this is fairly fluffy. It now has more ritual to it, and thus more meaning. But it is likely to accomplish little.
I could say that you need to cleanse your room, and your self, and your tools. Call in energy. Perform the task. Release energy. Thank. And leave the rocks to wait. Still, there is likely to be much effect. That is unless a person has much experience with the practice of doing such things.
Think of it like Riding a bike. It takes time to ride a bike. It takes time to learn the balance. It takes time to not use training wheels. More skill comes more ability. Some have more stamina. Some can do wheelies, bunny-hops, grinds, etc. Sure, a person might be able to ride a bike with out riding one in a long time. The old saying is: "you never forget how to ride a bike". But you probably lose some skill in your capabilities of the harder skills.
Magic is not just the ritual. It is not like baking a cake.
So, to answer your question, there is no such thing as a real spell of just the ritual, words, and tools. It is the act of the focus of the practitioner that brings about the change. Tools, words, and ritual are all methods for allowing the practitioner to focus themselves.
Someone with enough skill can make a spell out of very little.
At some point the person does it so much that it isn't even a spell anymore. It is simply moving things around where someone functions. A person can change the energy of a room or situation without much effort or thought, let alone a 15 minute ritual with rhymes and wands.
