As a cognate of the English word "secure," seguro has most of the meanings of "secure" as well as a few of its own. It is used most often to refer to safety, security, dependability, and certainly, concepts that overlap. The most common translations are "secure," "safe," and "certain," although others are possible.

Other Meanings for Seguro

Note again that the meanings above can overlap, and context may be necessary to determine what is meant. For example, one of the sentence above — Los teléfonos móviles ya no son seguros — came from an article about the security of information transmitted over the airwaves. But in a different context, the same sentence might have been referring to whether such cellphones can cause cancer.

Seguro as a Noun

As a noun, el seguro can refer to a safe place in general, or more specifically as a safety latch or other device that keeps something or someone safe. (In some regions, it can refer specifically to a safety pin.) A seguro can also refer to an insurance policy, especially one covering health or protection for injuries.
