Register: Very formal. Used primarily in:

  • Legal documents and contracts
  • Corporate bylaws
  • Government regulations
  • Official announcements

Hierarchical structure: In legal Japanese, (およ) and (なら)びに create a hierarchy:

  • (およ): connects items within a group (smaller units)
  • (なら)びに: connects groups (larger units)

Example structure

A(およ)B(なら)びにC(およ)D
= (A and B) AND (C and D)

This creates two groups: (A+B) connected to (C+D).

VS. (およ):

  • Both mean "and" formally
  • (なら)びに is more formal and connects larger units
  • In everyday formal writing, they are often interchangeable

Caution: Too formal for casual use. Even in business emails, (およ) or just is usually sufficient.
