Unique words in a text
Paste a text and get the alphabetical list of the distinct words, no duplicates.
What it's for
It gives the list of the different words in a text, each one once and in alphabetical order. It helps whoever is learning a language and wants the vocabulary of an article, whoever writes and wants to see how many different words they're really using, and whoever is putting together a list of terms for a glossary or an index.
How it counts
Words are counted as in the site's other counters: a piece between two spaces that contains at least one letter or digit. Every word enters the list in lowercase and without the punctuation stuck to its edges: «House», «house» and «house,» are the same entry and appear once. Numbers are entries too, so «12» and «3.50» appear in the list.
An apostrophe before a vowel splits: Italian «dell'anno» gives two entries, «dell» and «anno», which is almost always what you want, because «dell» is an article and not a word to study. Before a consonant it doesn't split, so «don't» stays a single entry; by the same rule «D'Amico» and «O'Hara» give two entries, «O'Neill» one. The alphabetical order is the one of the page's language, with accented letters next to the ones without an accent.
The same rule is used by Word counter, Reading time, Editorial pages and Word frequency: the number after «out of» is the same word total all five pages give, and the different words are the same ones Word frequency counts.
Different forms stay different words
The count is on written words, not on meanings: «cat» and «cats» are two entries, as are «go» and «went». Bringing them all back to a base form would mean knowing the grammar of every language, and irregular verbs would make it approximate anyway: better an honest list than one that's silently wrong.
Nearby tools
If besides the different words you need how many times each one appears, the page is Word frequency. For the total of words, characters and sentences there is Word counter, and to sort all the words keeping duplicates Sort the words. If the text is long and you want to know whether it reads easily, that count is done by How readable is a text.
