Merriam-Webster's Word of the Day for July 26, 2026 is "aerie." An aerie is primarily the nest of a bird of prey, like an eagle or hawk. These nests are typically constructed in elevated locations, such as on cliffs or mountain tops. The word can also describe a room or building situated high up. Such elevated structures offer a commanding view of the surroundings below. For instance, a lighthouse's aerie provides tourists with a bird's-eye perspective of the coastline. Historically, the term has been used for bird nests for centuries. Its origins trace back through Medieval Latin and Old French, potentially to the Latin word "ager" meaning "field." Over time, the meaning expanded to include human dwellings. Initially, this referred to homes placed high in mountains or hills. Today, the term is also used for high-rise city apartments and offices.
