Built from
雅 (yǎ, "elegant"),
洛 (luò, "Luo river"),
克 (kè, "to overcome") — all stock transliteration syllables.
雅 leads many name transliterations starting with "Ya-" (
雅典 Athens,
雅各 Jacob);
洛 covers "-lo-" (
洛杉矶 Los Angeles);
克 closes hard "-k" finals. Together they render "Ya-lo-k" with a deliberately refined feel.
