Sort the words
Paste a text and sort all its words alphabetically.
What it's for
It takes every word in the text, wherever it is, and lines them up alphabetically one after another, from A to Z or, if you pick it in the menu, from Z to A. It helps whoever prepares vocabulary lists to study, whoever has to sort a list of names typed in a rush, and whoever wants to see at a glance which words a text contains without reading all of it: in alphabetical order duplicates end up side by side and stand out immediately.
What counts as «a word»
A word starts with a letter or a digit and carries on with letters and digits; inside it can have an apostrophe or a hyphen between two of those, curly apostrophes included, and a point or a comma between two digits: that way «don't», «it’s», «well-known», «co-op», «mp3», «3D» and «3.5kg» stay whole. Accented letters count like all the others and the ordering puts them in the right place, because the comparison follows the rules of the English alphabet and not the characters' internal codes: «éclair» lands next to «eclipse», not at the very bottom. Numbers inside words are read as numbers, so «mp3» comes before «mp10».
As a result punctuation disappears and standalone numbers don't make it into the list: only a word with at least one letter counts, so «12», «2024» and «3.50» are left out, while «3D» stays in. That isn't an oversight: a vocabulary list with amounts and dates mixed in would be less useful, and there is a dedicated page for numbers.
The lines are lost, and that's on purpose
The result is a single text, with words separated by a space: the original split into lines is gone, because the words come from the whole text at once. If what you needed was to sort whole lines keeping them whole (a list of names, one per line), the right page is Sort lines. And if you need the list without duplicates, one word per line, there is Unique words, which splits words by its own rules: the two lists don't always match.
