The Portuguese word for reliable is confiável.

confiável is an adjective used to describe people, information or things that are fit to be relied upon.

What does it mean word for word?

The word is formed from the verb confiar (to trust) and the suffix -ável, which is equivalent to the English suffix -able.

In Portugal, fiável is an alternative form used to mean reliable.

To make the adjective plural, add -es to the end of the word to form confiáveis.

The word has 4 syllables, with the stress on the 3rd syllable: /kõ.fiˈa.vew/.

The root of the word relates to the concept of 'faith', meaning that to call something confiável is to say it is worthy of one's belief.
In Portuguese, you can describe a person as 'de confiança' instead of using the adjective confiável to imply they are a trusted confidant.
