spell checking and TeXworks

In case you already have LibreOffice installed, the en_US.aff and en_US.dic files are already on your system in the /usr/share/hunspell folder. In this case, just symlink these two files into /usr/share/myspell/dicts and you are done:

sudo ln -s /usr/share/hunspell/en_US.dic /usr/share/myspell/dicts/
sudo ln -s /usr/share/hunspell/en_US.aff /usr/share/myspell/dicts/

You can do so for all dictionaries you find in /usr/share/hunspell.

Restart Texworks afterwards.

You can see Texworks > Edit > Spelling > Unites-States now. Click it.

Also change Texworks > Edit > Preferences > Editor > spell-check-language > English-United-States.

You are done after restarting.

There is a section of the TeXWorks manual in which there is the reference to a guide on how to use dictionaries.

The link it refers to is this, so you should place your personal dictionaries in the folder /usr/share/myspell/dicts.

One easy way to add them is to install them. I suppose that if you use LibreOffice then they are installed by default. If not, you can simply install the packages named myspell-XX, where XX stands for your language.

You can easily find them with apt-get and auto-completion or via Synaptic.
