What is Apostrophe?
An apostrophe marks possession in many nouns and contractions in shortened forms; it does not normally create an ordinary plural.
What good apostrophe looks like
Correct apostrophe use depends on first deciding whether the word shows ownership, omission, or simple plurality, then applying the matching pattern consistently.
- Use apostrophe + s for most singular possessive nouns.
- Use an apostrophe after the s for most regular plural possessives.
- Use apostrophes in contractions to mark omitted letters.
- Do not add an apostrophe to ordinary plural nouns, years, or acronyms merely because they end in s.

When is guidance about Apostrophe ready to publish?
Publish when the writing decision is useful and the supporting source is appropriate to the claim: the strongest available source tier has been checked, material disagreement or uncertainty is named rather than hidden, examples do not imply invented facts, and any recommendation is no stronger than the evidence, story canon, authority, usage evidence, or verified project facts allow. If a consequential claim still depends on an unverified source, generated citation, disputed record, stale requirement, or unresolved contradiction, qualify it, revise it, or hold publication until the evidence improves.
Does every statement about Apostrophe need a recent source?
No. Freshness should match the claim type. Current policies, prices, roles, platform behavior, research findings, market conditions, and other changeable facts need current verification. Stable grammar, primary literary texts, manuscript canon, durable craft principles, and original illustrative examples may not need a recent citation at all. First classify the material as fact, interpretation, recommendation, convention, or original example; then use the strongest source and recency standard appropriate to that category, while preserving attribution and uncertainty where they matter.
When should I use a first-party or primary source instead of a secondary source for Apostrophe?
Use the first-party or primary source when the exact fact, quotation, current requirement, project/manuscript detail, policy, metric, or source text controls the conclusion. Use a strong secondary source when the job is synthesis, explanation, field-level context, or orientation and the secondary source is appropriate to that job. If a reader could act on the claim, if sources disagree, or if wording depends on an exact passage, number, rule, or current status, escalate to the controlling source of truth and record the source, version/date, and locator before publication.
Should Apostrophe show one “last updated” date or track verification at the claim level?
Use a page-level revision date for editorial history, but do not let it imply that every statement was reverified on that date. Changeable facts, quotations, policies, project facts, market data, provider capabilities, and other consequential claims should carry a source record with their own last-verified date or version and a specific recheck trigger. Stable editorial synthesis and original instructional examples can use the page revision/version record instead. When a material correction, retraction, or recommendation change affects what the reader should believe or do, retain the prior record and disclose what changed and why.
