Select the user-defined dictionaries and set the rules for the spellchecking.
Lists the available user dictionaries. Mark the user dictionaries that you want to use for spelling and hyphenation.
Opens the New Dictionary dialog, in which you can name a new user-defined dictionary or dictionary of exceptions and specify the language.
In the Dictionary section you can name a new user-defined dictionary or dictionary of exceptions and specify the language.
Specifies the name of the new custom dictionary. The file extension "*.DIC" is automatically appended.
By selecting a certain language you can limit the use of the custom dictionary. By selecting All the custom dictionary is used independently of the current language.
Specifies whether you wish to avoid certain words in your documents. In this way, you can create a custom dictionary of all the words to be avoided. If this exception dictionary is activated, during spellchecking you receive a corresponding note about any words which should be avoided.
Opens the Edit custom dictionary dialog, in which you can add to your custom dictionary or edit existing entries.
In the Edit Custom Dictionary dialog you have the option to enter new terms or edit existing entries. If you edit an exception dictionary, the dialog has the added facility of defining an exception for a word. During the spellcheck this exception is then listed as a suggestion.
When a dictionary is edited, a check is made on the status of the file. If the file is write-protected, it cannot be changed. The buttons New and Delete are then deactivated.
Specifies the book to be edited.
The IgnoreAllList entry cannot be selected and cannot be deleted. Only the words included as content can be deleted. This happens automatically each time that LibreOffice is closed.
Assigns a new language to the current custom dictionary.
You can type a new word for inclusion in the dictionary. In the list below you will see the contents of the current custom dictionary. If you select a word from this list it is displayed in the text field. If you type a word with a trailing = character, such as "AutoComplete=", the word is never automatically hyphenated and no hyphenation is suggested. Typing "Auto=Complete" results in the word being hyphenated, or a hyphenation suggested, where you insert the = sign.
You can use a  block instead of the = sign to specify character changes before the hyphenation break. Possible character changes: (1) Extra characters, for example tug[g]gumi results the correct hyphenation “tugg- gummi” of the Swedish word “tuggummi”. (2) Character removing specified by a digit, for example paral·lel results correct hyphenation “paral- lel” of the Catalan word “paral·lel”, removing one character before the break point. (3) Both removed and extra characters, for example cafee[2é]tje results correct hyphenation “café- tje” of the Dutch word “cafeetje”, removing two characters before the break point, and adding an extra one.
Replace By or Grammar By
This input field is only available if you are editing an exception dictionary or a language-dependent custom dictionary. In exception dictionaries, the field shows the alternative suggestion for the current word in the "Word" text box. In language-dependent custom dictionaries, the field contains a known root word, as a model of affixation of the new word or its usage in compound words. For example, in a German custom dictionary, the new word “Litschi” (lychee) with the model word “Gummi” (gum) will result recognition of “Litschis” (lychees), “Litschibaum” (lychee tree), “Litschifrucht” (lychee fruit) etc.
Adds the word in the Word text field to your current custom dictionary. The word in the Suggestion field is also added when working with exception dictionaries.
