The spelling of the Lithuanian word "radvilos" (RAHD-vee-laws) is derived from a noble family name "Radziwiłł" in the Polish language. The spelling of Lithuanian words is based on the Latin alphabet, and its diacritical marks indicate the stress placed on syllables. In "radvilos," the stress falls on the second syllable, which is represented by the diacritical mark above the letter "i." The Lithuanian language is unique in that it has a phonetic alphabet, meaning that each symbol has one sound, unlike English which has many exceptions and multiple ways to spell the same sound.
