Origin

The character 亭 appears to combine a roof or covering component at the top with the sound hint 丁, which suggests its pronunciation. The roof-like elements convey the idea of a structure or shelter, which aligns with the character's meanings of pavilion, cottage, or arbor—all small, freestanding buildings. The 丁 component doesn't contribute to the meaning but rather signals how the character should be read aloud. Over time, this visual design came to represent any kind of small architectural structure where people gather or dwell.
