およFormal and

およ formally joins nouns or noun phrases meaning “and.” It is used mainly in official, legal, academic, and technical writing, where the listed members are presented as included items rather than as mere examples.

Included members of a formal list

Use this connector when a document formally identifies the people, objects, requirements, or categories that belong in a list. In a list of three or more items, place it immediately before the final item.

Official and technical lists

たんまつおん湿しつおよあついっぷんごとにろくします。

The device records temperature, humidity, and air pressure every minute.

Analyze

The connector appears only before the final member of the three-item list.

List hierarchy in legal drafting

Legal documents may need to show which items form a subgroup. By convention, およ joins items within the smaller group, while ならびに joins that group to another group. Ordinary formal prose does not always maintain this distinction as strictly.

Included categories versus representative examples

およ formally coordinates the categories presented in the document. By contrast, gives representative examples and leaves open the possibility of other members.
