Translation guide
The English word "specification" covers several distinct concepts: a detailed description of requirements (often in technical or business contexts), the act of specifying something, and a specific requirement or standard. This guide helps learners choose the right Japanese expression based on the intended meaning.

Borrowed from English 'spec', commonly used for product specifications, especially in consumer electronics, cars, or computers. Often used in plural form スペック.
