Something that's open allows you to move or see through it, like an open window or an open gate.
The adjective open describes something that's not closed or blocked up, like open curtains that provide a view of the garden outside. Open can also refer to something that's unfastened or parted — an open jar of peanut butter, an open eye, or an open book. Things that are vulnerable, straightforward, or uncovered are also open, and if you are open to suggestions, it means you are willing to consider new ideas.
