How to say "compatibility" in Japanese
Choosing the right word
- 相性あいしょうnounCovers compatibility as personal chemistry: how well two people get along and suit each other. Choose this when 'compatibility' describes rapport between individuals rather than a technical or logical relationship.
- 両立りょうりつnoun, suru verb, intransitive verbCompatibility in the sense of coexistence: whether two things, aims, or demands can both be maintained without conflict. This, not 相性, is the word when 'compatible' means 'can coexist'.
- 適合てきごうno-adjective, suru verb, intransitive verbCompatibility as fit or conformity: whether something meets a standard, requirement, or specification. This is the technical sense; it is not used for the chemistry between people.
Use 相性 for the rapport or chemistry between people, 両立 when two things or demands can coexist, and 適合 for conformity or fit with standards, requirements, or specifications.
