Or you can add some authenticity to your story and do it the way real witches do it. We create Power Words.
I don't remember anymore what Donald Micheal Kraig said A.M.E.N. meant but it is a power word made of words needed to make a kabbalistic spell work correctly.

Lets say I needed a quick word to use while trying to heal someone using Reiki. I have a chant I use but I can't use it everywhere so I combine the words of the chant into a power word. Healing Within, Healing Without, becomes Hewihewo

Abracadabra is one of these power words again, I can't remember what it means because I don't use it but I've been told it works well. Anything you want to say or to create or to do you can turn into a power word. In the example I gave I took the first two letters from Healing and then the w from with and the I from in then the o from out and put them together. You can also just drop the vowel sounds or take the letters you emphasis when saying a word and put that letter with the other same type letters from other words.

You can give it some authenticity for the witches of the world and make creating words easier.
