# Dictionaries and Languages > Manage TX Spell .NET dictionaries in Windows Forms: Hunspell files, the Dictionaries collection, user dictionaries, multilingual text and language detection. - **Product:** TX Spell .NET for Windows Forms - **Section:** Documentation - **Kind:** Topic - **Path:** TX Spell .NET for Windows Forms > Dictionaries and Languages - **826 words** - **Web URL:** https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/ - **LLMs URL:** https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/llms.txt - **LLMs-Full URL:** https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/llms-full.txt --- What TX Spell .NET accepts as correct depends on its dictionaries. US English is included; every other language is a Hunspell dictionary that you download and load, and the words of your users go into user dictionaries. In documents that mix languages, the language of each piece of text decides which dictionaries check it, and language detection finds those languages when a text doesn't carry them. ![The Options dialog over TX Text Control Words with the Spell Checking Dictionaries tab, listing en_US.dic with the language English (United States).](https://docs.textcontrol.com/assets/img/tx-spell-dotnet-winforms/options-dialog-dictionaries.40842cf9.webp) ### How Dictionaries Work - **Dictionary files.** A language dictionary is a pair of Hunspell files, *.dic* and *.aff*, in the folder *Dictionaries*. Text Control offers tested dictionaries for about 40 languages. - **One collection.** The `Dictionaries` collection of the spell checker holds every dictionary it uses. A word is correct if an enabled dictionary of its language knows it. - **A default dictionary.** With the `Language` property at its default, "(Auto)", the spell checker loads the dictionary of the language the application runs in, or US English. - **User dictionaries.** Word lists with the extension *.txd* take the words users add with **Add To Dictionary**, and your code saves them for the next session. - **Languages of text.** TX Text Control stores a language with the text and passes it to the spell checker, so each part of a document is checked in its own language. The same folders hold the hyphenation lists and the thesaurus files, which [Hyphenation](https://docs.textcontrol.com/tx-spell-dotnet-winforms/hyphenation/llms-full.txt) and [Synonyms and Thesaurus](https://docs.textcontrol.com/tx-spell-dotnet-winforms/synonyms/llms-full.txt) cover. ### Find the Right Page | If you want to | Read | |---|---| | Know what a dictionary consists of and download more languages | [Hunspell and OpenOffice Dictionaries](https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/hunspell/llms-full.txt) | | Add, choose, switch off and remove dictionaries in code | [Loading and Managing Dictionaries](https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/managing/llms-full.txt) | | Let users add words, and keep them between sessions | [User Dictionaries](https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/user/llms-full.txt) | | Check documents written in several languages | [Multilingual Documents and Language Scopes](https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/multilingual/llms-full.txt) | | Find out which languages a text contains | [Language Detection](https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/language-detection/llms-full.txt) | | Check Arabic, Hebrew, Persian or Urdu | [Right-to-Left Languages](https://docs.textcontrol.com/tx-spell-dotnet-winforms/dictionaries/right-to-left/llms-full.txt) | ### Where to Start 1.
