cadena
/kaˈdena/ · A2 · noun · f
chain
⛓️📿 From Latin catena (chain) — same root as English concatenate: to chain together
Latin catena became cadena in Spanish (t softened to d) and chain in English via French. Concatenate literally means to link in a chain. A necklace is a chain worn on the neck; a TV network is a chain of stations.
