My co-worker and I are confused about the correct usage of the word information. We're writing an e-mail with the following sentence and need to know which one is the correct form and why:
All cost information have moved.
All cost information has moved.
The logic on the first example is that information is plural and if you changed information to documents you wouldn't say "All cost documents has moved"
Please enlighten us.
Information is not plural. It's a non-count noun that takes the singular form of the verb.
Other words that work that way include luggage, advice, and furniture.
Perhaps you are thinking of "data" which did use to be used with a plural verb (the singular form of the noun being "datum"). However, modern usage also treats data as a non-count noun and it's most often used with the singular form of the verb.
