tengku naming conventions

tengku have a childhood name given to them by their parents shortly after hatching. Typically these names are virtually unpronounceable to human tongues and sound like squawking crows or ravens to human or demihuman ears.   This name is generally only used in very private settings. Usually a tengku chick is addressed as "lad/lassie", "Son/Daughter" (regardless of whether the tengku addressing them is related) "Boy/Girl" "Young One", "You There!", or "Egg" (the latter is a term of endearment for close family only."       Upon reaching adulthood, a tengku will choose a new name.   Most tengku names are two syllable names with strong vowel sounds.   It is tradition for a tengku to choose one vowel sound from their father and one from their mother. If a tengku does not do this, he or she is often but not always signaling "I have issues with my parents."   This is pretty common as tengku are notorious for favoring "tough love" parenting styles, so this results in a lot of young adults swearing off their parents (they may or may not reconcile later, but the rebellious name stays post-reconciliation).
