Other forms: gazebos
A gazebo is a small, freestanding, outdoor structure that has a roof but is open on all sides. If it starts raining suddenly while you're walking through the park, you can run to the gazebo to get out of the rain.
Gazebo is unusual in that it's an imitation Latin word. Experts believe it comes from a joking twist on the word gaze, as in "I gaze at you from my gazebo." It's meant to sound Latin, modeled after words in the future tense that end with the suffix -ebo, like videbo, "I shall see." If you want to gaze at your yard from an octagonal covered porch, you should consider building a gazebo.
