This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "perimenopause" in a final draft.
If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.
Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "perimenopause" as the right word for your sentence.
If your draft is formal, technical, persuasive, or sensitive, compare "perimenopause" with a nearby alternative so the final choice matches both meaning and reader expectation.
Check whether "perimenopause" is acting as noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.
Compare it with a nearby word before publishing so the final choice matches the reader's expectations.
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
