flying, assist, help, respect
翊 centers on the idea of supporting movement or action: assisting, helping, or showing respect by aiding someone, with an underlying image of flying alongside or lifting up.
翊 combines 立 (stand) and 羽 (feathers/wings), suggesting standing wings or aiding flight. The exact historical development is uncertain, but the components likely work together to express assistance or support.
Picture a bird standing (立) with its wings (羽) spread, ready to help another bird take flight. 翊 is about assisting and lifting others up.
For ヨク, imagine a yoke (ヨク) used to help two oxen pull together: the yoke assists them, just as 翊 means to assist.
