If you have typed define:collate into a search box, you are asking for a precise definition, and the answer is pleasingly concrete: to collate means to gather and arrange separate items into a proper, ordered sequence. The word is most familiar from printing and office work, where collated pages are assembled in page order rather than left in separate stacks, but it also appears in bookbinding, data processing, and everyday language about organising material. This guide gives the full definition, shows how the word is used in each of its main contexts, and clears up the common confusions with similar words.
The reason define:collate is such a useful search is that collate is one of those words people recognise instantly yet struggle to define on the spot. Most of us have seen a printer setting labelled collate, or heard someone ask whether a handout has been collated, without ever stopping to put the meaning into words. Once you understand the core idea, which is gathering plus ordering, every use of the word falls into place, from a photocopier menu to a database manual. The rest of this guide builds on that core idea, context by context. That core idea is what a search for define:collate is really trying to pin down.
Define:collate in Plain English
To define:collate in the simplest possible terms, collate is a verb meaning to collect separate pieces and put them together in the correct order. If you have ten copies of a five-page report, an uncollated set gives you ten copies of page one, then ten copies of page two, and so on, while a collated set gives you ten complete reports, each running from page one to page five. The difference is entirely about order: collation is the act of turning loose, unordered pieces into finished, sequential sets.
The word comes from Latin roots connected with bringing things together, and that history still shows in modern usage. Collating is never just piling things up; it always involves arranging them according to some sequence, whether that sequence is page numbers, alphabetical order, chronological order, or a custom order set by the person doing the work. If there is no ordering step, the work is gathering or collecting, not collating. That distinction is the key to using the word correctly, and it is also why define:collate searches so often come from people who want to check a printer setting before they waste paper. Keeping that boundary clear is the main payoff of looking up define:collate.
Collate Versus Collect
Collect means to bring things together, while collate means to bring things together in order. You collect stamps into an album; you collate the pages of a report into numbered sequence. You collect survey responses; you collate them into a single ordered dataset for analysis. Keeping that contrast in mind will prevent most misuse, and it explains why the word survives in technical fields where order matters more than mere accumulation.
Define:collate in Printing and Photocopying
The printing context is where most people meet the word, and it is also where define:collate has the most practical payoff. When you print multiple copies of a multi-page document, the collate setting controls whether the printer outputs complete sets or grouped pages. With collation on, the printer produces copy one in full, then copy two in full, and so on. With collation off, it produces all copies of page one, then all copies of page two, which leaves you to sort the sets by hand. For any document longer than a couple of pages, collation on is almost always the right choice, unless you deliberately want grouped pages for separate distribution.
The same idea applies to photocopiers, booklet makers, and print finishing equipment, where collating machines, sometimes called collators, mechanically assemble pages into sets before stapling or binding. In a busy office, choosing the wrong setting can turn a two-minute print job into twenty minutes of manual sorting, which is why the setting is worth understanding rather than ignoring. If you are preparing handouts for a meeting, a class, or an event, check the collate option in the print dialogue before you press print, and do a single test copy first when the document is long or the stakes are high. That single check is the most practical reason anyone searches define:collate before a large print job.
Collate in Books, Data, and Research
Beyond printing, collate appears in several specialised contexts that all share the same core meaning. In bookbinding, collating is the process of checking that all the folded sections of a book are present and in the right order before they are sewn or glued together, a quality-control step that prevents missing or duplicated pages. In data processing, collation refers to the rules that determine how text is ordered and compared, such as whether capital letters sort before lower-case letters, or how accented characters are treated, which matters enormously when sorting large lists. The same ordering idea behind define:collate in printing applies in bookbinding, where a missed section is caught by collation.
In research and archival work, to collate sources means to bring different versions, copies, or accounts together and compare them systematically, often to establish the most reliable text or the fullest picture of an event. A historian might collate several manuscripts of the same work to see where they differ; a scientist might collate results from multiple studies before drawing a conclusion. In each case the work is the same: gather the pieces, arrange them in a meaningful order, and check them against each other. For more word guides in this style, see our explanations of all-encompassing meaning and animosity meaning, which follow the same plain-English approach. That shared pattern is why define:collate appears in fields as different as printing and research.
Examples of Collate in Use
The table below shows the word in its main contexts, so you can see at a glance which meaning applies to the situation you are dealing with. Notice how the ordering element is present in every row, even though the material being ordered changes completely.
| Context | Example sentence | What is being ordered |
|---|---|---|
| Printing | Please collate the reports before stapling them. | Pages into complete copies |
| Bookbinding | The binder collated the sections before sewing. | Folded sections into book order |
| Data sorting | The database uses a collation that ignores case. | Text values into sort order |
| Research | She collated the survey results by region. | Responses into a structured set |
| Everyday office work | He collated the handouts into packs for each table. | Loose sheets into ordered packs |
Related forms of the word follow the same pattern. Collation is the noun for the act or the resulting order, collated is the adjective for material that has been put in order, and a collator is a person or machine that does the collating. If you remember the verb first, the related forms take care of themselves, because they all point back to the same idea of gathering and ordering. A document described as collated has been through that process; a document described as uncollated has not, and will need sorting before it is usable as a set. Once you can answer define:collate for the verb, the noun and adjective follow naturally.
Common Confusions and Similar Words
Collate is sometimes confused with a handful of similar words, and sorting them out is worth a moment. Collate is not the same as collect, as explained above, because collect lacks the ordering step. It is not the same as compile, which means to assemble material from various sources into a single work, often with editing, whereas collate is specifically about ordering what is already there. It is also distinct from correlate, which means to show a relationship between two things, and from corroborate, which means to support a statement with independent evidence. The sounds are similar, but the meanings are different, and swapping them will confuse a reader.
Another common question is whether collate can be used for abstract things, such as ideas or arguments. The answer is yes, but sparingly: you can collate notes, evidence, or findings, because those are items that can be ordered, but describing a purely mental process as collation can sound forced when a simpler word such as organise would do. The best test is whether the sentence still makes sense if you substitute the phrase “gather and put in order”. If it does, collate is a good choice; if it does not, choose a simpler verb. That test also helps when you are deciding whether a document needs collating at all, or merely needs tidying.
Frequently Asked Questions
What does collate mean on a printer?
On a printer, collate means print complete sets in page order, so each copy runs from the first page to the last. With collation off, the printer groups identical pages together, and you must sort the copies into sets yourself.
How is collate pronounced?
Collate is pronounced with the stress on the second syllable, in the style of kuh-LAYT. The noun collation stresses the same syllable, while the adjective collated follows the verb naturally.
What is collation in computing?
In computing, collation is the set of rules that determines how text is sorted and compared, including case sensitivity, accent handling, and character order. Different collations can produce different sort orders for the same data, which is why database and spreadsheet settings sometimes include a collation option.
Is collate a formal word?
Collate is a standard, slightly formal word rather than slang, and it is at home in office, academic, and technical writing. In casual conversation, people often say “put in order” instead, which is equally correct and sometimes clearer. For another meaning guide, see our page on acceded meaning.
Define:collate in One Sentence
If you need define:collate answered in a single sentence for a note or an exam, use this: to collate is to gather separate items and arrange them in their proper order. That sentence captures define:collate completely, because it contains both halves of the meaning, gathering and ordering, and it works as a test for every context in this guide. Apply it to a printer, a bookbinder, a database, or a research project, and define:collate will give you the same answer each time.
Conclusion
To return to the search that started this guide, define:collate means to gather separate items and arrange them into a proper, ordered sequence. Whether you are printing a report, binding a book, sorting data, or organising research, collation is the step that turns a pile into a usable set. Remember the printer test: collated copies are complete from first page to last, uncollated copies are grouped by page and need sorting by hand. With that image in mind, you will use the word correctly, set your printer with confidence, and recognise the same ordering idea wherever the word appears next.
