The kanji 騰 is a 形声文字 (keisei moji), a phono-semantic compound. The phonetic component is 朕 (chin/ten), and it's combined with 馬 (uma/ba) meaning "horse." The 馬 (horse) component provides the semantic element (relating to movement or activity). The original meaning related to a horse leaping or jumping. Over time, the meaning broadened to include rising and soaring. The combination suggests a horse jumping or rising up high, representing the upward movement or increase.
