centroj

centroj is the plural form of centro in Esperanto and refers to centers in a broad sense: geographic centers, focal points of activity, or the central parts of objects or spaces. The singular form centro denotes a single center, while centroj denotes multiple centers, which may be geographic, social, cultural, or functional in nature.

Etymology: The Esperanto centro is borrowed from Latin centrum, via French centre or Italian centro. In Esperanto, nouns end in -o and the plural is formed with -oj, so centroj is centro + -j. The word follows standard Esperanto morphology and has no gender.

Usage: centroj is used in geographic, architectural, and organizational contexts. For example, la centro de la urbo means the city center, and centroj de urboj means the centers of cities. Compound forms such as kulturcentroj (cultural centers) or komercaj centroj (commercial centers) illustrate how centroj appears in plurals within longer terms. In abstract discourse, centro denotes a focal point, as in la centro de agado (the center of activity) or la centro de atento (the focus of attention).
