What does navigability mean?
Navigability describes how easily a person can move through, understand, or find a way around a place, system, website, or network. A well-designed airport, road network, or online catalogue has good navigability because its routes, labels, and structure make choices clear. The term is especially associated with user experience and information architecture, where designers seek to reduce confusion and help users reach useful destinations quickly. It can also describe the practical ease of moving through physical environments such as buildings, trails, or public transport systems. Although navigability is related to accessibility and usability, it focuses more specifically on orientation and movement. In general, high navigability suggests that a system is logically organized and easy to understand, whereas poor navigability results in difficulty locating entrances, routes, controls, or relevant information.

Where does navigability come from?
Navigability is formed from navigable, which in turn comes from the Latin navigare, meaning “to sail,” “to travel by ship,” or “to steer a course.” The underlying root is navis, meaning “ship,” which also appears in related English words such as navigation and navigator. The suffix -able developed to indicate that something can be navigated, while the suffix -ity was added to form the noun navigability. The concept originally concerned movement by water, but modern usage extends it to roads, buildings, networks, and digital environments.
