strong and brave
赳 centers on a person who is physically strong and courageous, combining vigor with bravery.
赳 combines 走 (run) with 丩, which likely contributes a phonetic element. The character is associated with a strong, brave manner of moving or acting.
The running radical 走 suggests movement, and the inner 丩 looks like a sturdy, upright figure. Picture a brave warrior running forward with strength.
For キュウ, imagine a strong, brave person letting out a sharp 'kyu!' sound as they charge forward: kyu -> キュウ.
