| sense | extracellular vesicle, 2018 - `particles naturally released from the cell that are delimited by a lipid bilayer and cannot replicate`. THE WORD `naturally` OCCURS EXACTLY ONCE IN THIS DOCUMENT, here, and MISEV2023 minutes its removal `to avoid unintended exclusion of engineered EVs`. A category boundary edited in public, one word, five years apart, and both texts are now in this corpus— “ISEV endorses “extracellular vesicle” (EV) as the generic term for particles naturally released from the cell that are delimited by a lipid bilayer and cannot replicate, i.e. do not contain a functional nucleus.” | senses[0] |
| sense | operational term - a name that states what was MEASURED: size (sEV under 100 or 200 nm, m/lEV over 200 nm), density, biochemical composition, or cell of origin. THE FIELD RETREATS FROM A HISTORY TO A DIAMETER, with the ranges required to be stated— “physical characteristics of EVs, such as size (“small EVs” (sEVs) and “medium/large EVs” (m/lEVs), with ranges defined, for instance, respectively, < 100nm or < 200nm [small], or > 200nm [large and/or medium]) or density (low, middle, high, with each range defined)” | senses[1] |
| sense | exosome / microvesicle, 2018 - terms to be used IN THE PLACE OF NOTHING: the document asks authors to put operational terms `in the place of` these, and if that is unavoidable, to define them `clearly and prominently at the beginning of each publication`. A vocabulary conceding that its words carry no shared meaning— “If it is deemed unavoidable to use these or newly coined terms, they should be defined clearly and prominently at the beginning of each publication” | senses[2] |
| sense | extracellular particle (EP) - the honest fallback. Where EV identity cannot be confirmed to this document's minimal requirements, the claim of vesicularity is dropped rather than asserted weakly— “If confirmation of EV identity cannot be achieved according to the minimal requirements of this MISEV2018 publication, other terms such as extracellular particle (EP) might be more appropriate.” | senses[3] |
| sense | `exosome` / `microvesicle` - RETIRED BY A CONSORTIUM, AND THE STATED REASON IS TWO FAULTS AT ONCE: `terms such as exosome and microvesicle that are historically burdened by both manifold, contradictory definitions and inaccurate expectations of unique biogenesis.` The first fault is that the word means different things to different authors; the second is that it means something the experiment did not show. A name can be ambiguous without being presumptuous, and these are charged with both.— “in the place of terms such as exosome and microvesicle that are historically burdened by both manifold, contradictory definitions and inaccurate expectations of unique biogenesis.” | senses[4] |
| sense | THE REPLACEMENT IS A CHANGE OF KIND, NOT A CHANGE OF WORD: an ORIGIN-based vocabulary is swapped for a MEASUREMENT-based one. `operational terms for EV subtypes that refer to a) physical characteristics ... such as size (“small EVs” (sEVs) ...) or density ...; b) biochemical composition ...; or c) descriptions of conditions or cell of origin ... in the place of terms such as exosome and microvesicle`. Every replacement names something the experimenter can measure; the retired terms named where the vesicle came from.— “Therefore, unless authors can establish specific markers of subcellular origin that are reliable within their experimental system(s), authors are urged to consider use of operational terms for EV subtypes that refer to a) physical characteristics of EVs, such as size (“small EVs” (sEVs) and “medium/large EVs” (m/lEVs), with ranges defined… | senses[5] |

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
