Forgive the long post.
The Kamawenõ name their children by first consulting one of their people gifted with precognition to discover some aspect of the child's future personality or history. (Asking a seer about the future in any other case, including for military purposes, is strictly forbidden.) They then give them a name based on what they see, and in doing so further encourage the child to follow the path that will lead them to that name in the future. (In formal speech, a person's name must be preceded by the honorific El. Also, the accents marking irregular stress and therefore modifiers are reversed, helping to distinguish them from modifiers that may refer to the person, but aren't a part of their name.)
They have family names, made of two halves, with one being their mother's female family name and the other being their father's male family name. If they are female, their mother's name goes first - if they are male, the opposite is true.
They also have a more commonly used 'nickname', which is formed through some jumble of syllables from their actual name. It is always far shorter, and always complete gibberish. For example:
El Rādovùlkamaòrdōzuskamākenomìk Korasa-Nans-Woranalbēàn - roughly "Female Child Who Can Be Compared To A Raven On Its First Flight, Of The Family Nance and Red Wing".
Nicknames would include Rāmik, Dovu, Rāvu, Romik, Rik, Rā, etc. None of these words mean anything.
Names in Genljøŋ are formed by a string of nouns and modifiers (it's agglutinative, so this is easy) followed by a male or female suffix. Examples (from How to Train Your Dragon - don't look at me like that):
Toothless: Jelïlum (Toothless)
Hiccup: Hiqag (Hiccup) [Hiqernum??] (to Hiccup)
Stoic: Bøümør (Steady)
Astrid: Östrid (Sun)
Fishlegs: Gatätølegar (Fishlegs)
Snotlout: Nøsøm (Nose)
Gobber: Qjiqernug (Spitting)
Tuffnut: Dagrag (Tough)
Ruffnut: Nagrad (Rough)
Names in HyPry are complicated. At birth or looming, one is given a name that is usually quite poetic and a little prophetic. At least one of the words in their name must be a noun. (Let's say C Roumonó Lùndor, 'Insulted Infinity'.)
At any point, their names may be condensed, in which the articles and any tonal information are removed. This can change the meaning of a name, but is a concise and informal way to refer to someone. (Roumonolundar, 'Insult Infinity'.)
When they are accepted into the House by the family, usually several weeks after birth, they add their House name into their own, and their birth name is confirmed in what is called the Nameday. (C Roumonó Cou Dvourœtre Lùndor, 'Insulted Infinity of Dvora'. Short form: Roumonodvourœtrelundor.) This is now their full, mature name, and is what they are called in most informal situations.
[One should note that the person whose name I'm using as an example here wasn't actually from the House of Dvora - they were from the House of Heartshaven - but after little-known and well-covered-up scandal in which the cousin whom she was intended to replace wasn't actually dead after all, her House exiled her from the family. One of the cousins in the House of Dvora suspected she would do great things, and since one of their other cousins had recently died with no one yet loomed to replace him, they gave her a second Nameday and, legally, changed her house. But I digress.]
At eight years old, when they enter the Academy, they gain the title of their Chapter, which is incorporated into their name.
As they grow and reach certain life milestones, their name becomes increasingly long, and is sometimes rearranged. I will again use Romana as an example.
After entering the Academy (Prydonian Chapter): C Roumonó Cou Dvourœtre Côû Proıdounıœtʃôû Lùndor
After first regeneration: C Roumonó Íétȷʃo Cou Dvourœtre Côû Proıdounıœtʃôû Lùndor
After reaching 600 years of age (by the Gallifreyan time scale): C Roumonó Íétȷʃo Cou Dvourœtre Côû Proıdounıœtʃôû Kîêm Lùndor
After second regeneration: C Roumonó Íédȷʒın Cou Dvourœtre Côû Proıdounıœtʃôû Kîêm Lùndor
[The regeneration count continues through all twelve regenerations, essentially 'deaths'... and beyond, if their cycle is renewed. We only see three of Romana's, however.]
After becoming Lady President of Gallifrey: C Lıeloug Roumonó Íédȷʒın Cou Dvourœtre Côû Proıdounıœtʃôû Kîêm Lùndor
After reaching 6000 years of age (by the Gallifreyan time scale): C Lıeloug Roumonó Íédȷʒın Cou Dvourœtre Côû Proıdounıœtʃôû Kǐět Lùndor
And so on and so fourth. Note that these lengthened names can still be shortened (Lıelougroumonoıedȷʒındvourœtreproıdounıœtʃoukıetlundor), but this is rare, and generally one would simply use the shortened form of one's original mature name (in this case, Roumonodvourœtrelundor. Or Romana. Or Fred.)
