Source and review context

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 "folio" 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.

Before you rely on this definition

Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "folio" as the right word for your sentence.

If your draft is formal, technical, persuasive, or sensitive, compare "folio" with a nearby alternative so the final choice matches both meaning and reader expectation.

Compare nearby meanings

  • Use synonyms when you need a softer, stronger, simpler, or more specific word.
  • Use antonyms to check the boundary of the meaning and avoid accidental contrast.
  • Use the example sentence to confirm the word behaves naturally in context.
  • Keep the original wording when a replacement adds complexity without improving precision.

Definition decision workflow

1. Identify the role

Check whether "folio" is acting as noun, verb in your sentence. A definition is only useful when the grammar matches the way the word is being used.

2. Test the nearest option

Compare it with "leaf" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.

3. Confirm with context

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.

Final meaning check

Before publishing a sentence with "folio", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.

When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

    "[Thomas] Hood also presented his treatises in such a way that conveniently accessing specific lessons was difficult, if not impossible, for the reader-practitioner. For example, his book entitled The Vse of Both the Globes, Celestiall and Terrestriall... (1592) was roughly two hundred pages long but did not include such helpful tools as an index, a table of contents, or even folio numbers. In order to refer to some lesson that he might need, the reader would have to leaf through the text until the passage in question was found, or else rely upon his own marginal notes."

[…] [page 176] The Cursitors have claimed before us a right to compute the skin in all cases, at twenty folios, each folio containing seventy-two words; and to charge 1 s. 4 d. for every folio, instead of the fees now taken per folio or per skin, where the writ in charged in that manner. In support of this claim they have contended, that twenty folios of seventy-two words each, were established by the Order of 1743, as the length of a skin; […] The writ [of Transgress' super Casum], exclusive of the part containing the matter of the declaration, contains less than two folios of seventy-two words each; common counts are stated to contain usually, from two to three folios; special counts are usually longer, and sometimes of a much greater length."

Etymology

From Middle English folio (“leaf of a book”), borrowed from Medieval Latin foliō, Late Latin foliō, Latin foliō, the ablative singular form of Late Latin folium (“leaf or sheet of paper”), Latin folium (“leaf of a plant”), ultimately from Proto-Indo-European *bʰleh₃- (“bloom, flower”). Doublet of foil and folium, and distantly related to phyllo and phyllon. Senses 1, 2, 3.1, 5, and 6 relating to a leaf or page are derived from Medieval Latin foliō in references; sense 5 (“page in an account book”) may be derived from Italian foglio (“rectangular sheet of paper”), from Latin folium. Senses 3.2 and 3.3 relating to a paper size are from Italian in foglio or its etymon Latin in foliō.
