relaxed, at ease, place
攸 centers on a state of ease and relaxation, often in a particular place or setting. The 'place' meaning is an extension of being settled or at rest somewhere.
攸 is an older character whose exact historical development is uncertain. It visually combines a person-like element on the left with 攵 (a hand holding a stick) on the right, but the original meaning connection to 'relaxed' or 'place' is not clearly established from these components.
Imagine a person (the left side) resting under a tree while a hand with a stick (攵) gently prods them to stay relaxed. The scene creates a sense of being at ease in a quiet place.
For ユウ, picture a relaxed person saying 'you' as they invite you to join their peaceful spot: you -> ユウ, and you feel at ease.
