妥 compromise

You compromise with your DAD about when you can borrow the car.

The man wanted a huge aerie of vultures but the woman compromised on a small nest.

compromise ★★★☆☆
妥 (compromise) + 協 (cooperate) = 妥協 (compromise)

adequate ☆☆☆☆☆
妥 (compromise) + 当 (hit the target) = 妥当 (adequate)

means 'appropriate' - but more relaxed than related words like 適当 (てきとう)　and 正しい (ただしい). . .妥当 is more like "adequate."
