óáreiðanleg

áreiðanleg is an Icelandic adjective meaning reliable, dependable, or trustworthy. It is used to describe people who can be counted on, as well as devices, systems, information, or processes that perform as expected. In everyday language and in technical or consumer contexts, áreiðanlegt denotes consistency and a low risk of failure or unpredictability.

In Icelandic, adjectives inflect for gender and number. The base form is áreiðanl- with typical endings such as áreiðanlegur (masculine singular), áreiðanleg (feminine singular), and áreiðanlegt (neuter singular). Plural forms include áreiðanlegir (masculine), áreiðanlegar (feminine), and áreiðanlegt (neuter), depending on the noun they modify. As a predicative complement, one can say, for example, "Kerfið er áreiðanlegt." The noun form of the concept is áreiðanleiki, meaning reliability or dependability.

Nuance and usage: áreiðanleg emphasizes consistent performance and predictability over time, rather than merely current credibility. It is commonly used for technical equipment, software, services, and personnel, especially in contexts where steadiness and trustworthiness are important.

Related terms include trúverðugur (credible, trustworthy in a broader sense) and öryggur/öruggur (safe or secure), which highlight different aspects of trust or safety. Áreiðanleg is a core descriptor in product reviews, reliability assessments, and quality assurances within Icelandic discourse.
