Wiktionary:Entry layout explained
An entry or definition page contains every piece of dictionary information that directly relates to a specific word or phrase. The rules about organization are somewhat complex, but they result in articles that are easy to read.
While the information below may represent some kind of "standard" form, it is not a set of hard rules. You may try different ways of organizing a page but other users might revert those changes. They have just as much right to do that as you have to make them. Be ready to talk about those changes. If you want your way to be accepted, you have to have a good reason for it. Unless there is a good reason, the standard will be followed.
