Expert writing Tips
Best practice
When describing the composition of something, use "are made of" instead of "are of" for better clarity and grammatical correctness. For instance, say "The walls are made of brick" instead of "The walls are of brick".
Common error
Avoid using "are of" to indicate possession. Instead, use the possessive form "belong to" or "possess". For example, instead of saying "These ideas are of John", say "These ideas belong to John".

Ludwig's WRAP-UP
While the phrase "are of" appears frequently across diverse sources such as news articles, encyclopedias, and scientific publications, it is flagged by Ludwig AI as grammatically incorrect. Although it is widely used to indicate relationships of composition, origin, or characteristics, better alternatives include phrases like "are made of", "consist of", or more specific verbs like "exhibit" or "display", especially in formal writing.
