The words that I put up here, in vertical or horizontal form, are made with an omnidirectional alphabet invented for science fiction purposes. The words are meant to be used in a zero-g environment where there is no up or down, because there is no gravity.
Since I invented this alphabet in just a few years it is a constructed alphabet, and not a natural one, like the Roman alphabet or the Cyrillic alphabet. They slowly evolved over many centuries.

Last week I was presenting the alphabet with the word POLIORCETICS.

This word refers to the art of laying a siege to a castle, a city or a fortress or of resisting to such a siege.

This week there are 10 letters in 2 groups of five because they make up the first name and last name of a person famous in the world of science fiction.

You can find out the meaning of the 10 letters presented this week by comparing with other words whose letters you know or by using this list of letters from A to Z:

Or, you can wait until next week, when I will reveal what the letters mean.
