The Spanish word 'cadenita' meaning 'small chain' comes from the Spanish word 'cadena' ('chain') combined with the diminutive suffix '-ita'. The word 'cadena' itself derives from the Latin word 'catena', which also meant 'chain'. The diminutive suffix '-ita' is commonly used in Spanish to indicate something is small or endearing.

The most obvious related Spanish word is 'cadena', which simply means 'chain'. While 'cadenita' specifically refers to a small chain, 'cadena' is the general term for chains of any size. You might encounter 'cadena' in contexts like 'cadena de montañas' (mountain chain) or 'cadena de televisión' (television channel/chain).

The English word 'chain' is not directly related to 'cadenita', as it comes from a different root. However, English has borrowed some words from the Latin 'catena', such as 'concatenate' (to link things together in a chain or series) and 'catenary' (the curve that a chain or rope makes when hanging freely between two points). These technical terms preserve the connection to the original Latin word for chain.
