Lucis is a first name for boys.
Recently, the name Lucis has been given only a handful of times a year and is therefore particularly rare, at least in the US. In recent years, not even one boy in 100,000 has been named Lucis. That means that a boy named Lucis is exceptional and may not meet another person with the same name his whole life.
Well, you might say, you probably figured that out yourself! But what you might not know is: The letter L is neither particularly common nor particularly rare as a first letter for boys' names: 4.1% of all common boys' names in the US begin with this letter. By the way, the most common first letters of boys' names are J and A, while X and U are the least common initials of boys' names.
With five letters, the name Lucis is comparatively short. In fact, 17.0% of all common first names in the US consist of exactly five letters. Only 7% of all first names are even shorter, while 75% have more than five letters. On average, first names in the US (not counting hyphenated names) are 6.5 letters long. There are no significant differences between boys' and girls' names.
Thus, it follows that with 4.1% of all boys' names starting with an L, this initial letter occurs about as often as all 26 letters on average. Nevertheless, there are boys' names with L that are quite common, the most common in the U.S. at present is Larry.
If your name is Lucis and someone asks after your name, you can of course just tell them what it is. But sometimes that isn't so easy - what if it's too loud, and you don't understand them well? Or what if the other person is so far away that you can see them but not hear them? In these situations, you can communicate your name in so many other ways: you call spell it, sign it, or even use a flag to wave it...
So that everyone really understands you when you have to spell the name Lucis, you can simply say:
Braille is made up of dots, which the blind and visually impaired can feel to read words.

These flags are used for maritime communication - each flag represents a letter.
In the navy, sailors of two ships might wave flags to each other to send messages. A sailor holds two flags in specific positions to represent different letters.
In Morse code, letters and other characters are represented only by a series of short and long tones. For example, a short tone followed by a long tone stands for the letter A. Lucis sounds like this:
