I got two tables, books and words.

A book has many words.

However a work is not belong to a book, because a word can be used in different book.

Which association is right for this case?

Many thanks for reply.

has_and_belongs_to_many

or use an explicit join table and has_many :through.

See the Rails Guide on ActiveRecord Associations for the basics of using various associations.
