agree
潝 centers on agreement, possibly in a flowing or harmonious sense suggested by the water radical. The single given meaning is narrow, and the kanji is rare, so treat its core idea as uncertain.
潝 combines 氵 (water) with 翕, which likely contributes the sound and possibly a sense of gathering or uniting. The exact historical development is uncertain.
Water 氵 flows together with 翕, like streams merging in agreement. Picture two rivers joining smoothly into one.
For キュウ, imagine a queue of water droplets all agreeing to flow in the same direction: queue -> キュウ, and the water 氵 unites them.
