The word is derived from the verb 'sich verlassen auf' (to rely on). If someone or something is 'zuverlässig' (reliable), you can rely on them or it. The ending '-ig' turns it into an adjective.

'sicher' and 'zuverlässig' can both mean that you can trust a thing or a person. 'sicher' fits well when something works, does not make mistakes, or is guaranteed. 'zuverlässig' more often describes that someone or something repeatedly does what you expect. A reliable person, for example, arrives on time and keeps promises. A reliable or safe device works without major risk or errors. Often the two words are close in meaning, but 'zuverlässig' emphasizes lasting dependability more.
