nietbruikbare

Nietbruikbare is a Dutch adjective meaning unusable or not usable. It is formed from the negation niet and the adjective bruikbaar (usable). The term designates objects, materials, information, or opportunities that cannot be used for their intended purpose, whether permanently due to defects or temporarily due to circumstances.

The word is typically used in attributive position before a noun, for example: een nietbruikbare machine, nietbruikbare onderdelen, of nietbruikbaar materiaal. In predicate position one would normally say het is niet bruikbaar or de machine is niet bruikbaar. The form nietbruikbare is the feminine singular or plural inflected variant used before a noun, while the predicate form often uses the separate adverbial phrase niet bruikbaar.

Nietbruikbare is common in professional and practical contexts such as inventory and procurement, maintenance reports, or risk assessments, where items may be deemed unsuitable for their intended use. In information technology or data management it can refer to files, software, or data sets that cannot be used for a specific task or need to be discarded.

Differences with onbruikbaar: onbruikbaar tends to convey a stronger or more permanent incapacity, often due to damage or fundamental inoperability, whereas nietbruikbaar can indicate situational or conditional unsuitability. Both terms reflect unavailability for use, but their nuance varies with context and degree of usability.
