This character combines 木 (tree) and 冓 (an old form related to assembling). The original meaning was to build something by joining wood together, later expanding to abstract uses like “structure,” “format,” or “take position.” It can also mean “to care” or “to mind” someone’s actions, showing the flexibility of its use.

彼は家いえを 構かまえて、静しずかに暮くらしている。
He built a house and lives quietly.

そんなこと、気きに構かまうな。
Don’t worry about that.

Common on-yomi is コウ, as seen in words like 構成 and 構造. The kun-yomi かまえる and かまう are also frequently used in both written and spoken Japanese.
