What does inroad mean?
An inroad is an advance into someone else's territory, market, or area of influence. Although the singular form exists, the noun is now encountered chiefly in the plural, as in “make inroads into,” when describing a company gaining customers, a movement gaining supporters, or a power extending its reach. The word often implies gradual or determined penetration rather than a sudden attack. In older usage, an inroad could also mean a route or means of entry into a place. Today that physical sense is uncommon, while the figurative sense is especially prominent in business, politics, and cultural commentary. The term is more formal than everyday alternatives such as “break into,” though it can suggest persistence and an increasingly strong position.
