Translation guide
The English word 'disinterested' has two main meanings: (1) impartial, unbiased, having no personal stake; and (2) uninterested, not interested. These meanings are often confused even by native speakers. In Japanese, different words are used for each sense.
Describing a person, decision, or opinion that is fair because they have nothing to gain or lose.
Most common word for 'fair' or 'impartial'. Used for people, judgments, and treatment.
Describing a lack of interest or concern. This meaning is often considered nonstandard in English but is very common.
In careful English, 'disinterested' means impartial, while 'uninterested' means not interested. However, many English speakers use 'disinterested' to mean 'uninterested'.
