Parley lets you associate word types with the words. Word types are for example: Nouns, Verbs, Adjectives and Adverbs.
In order to work with word types, enable the word type tool: → .
You can categorize the word types just like lessons.
If you want to see all words of a certain type - e.g. all nouns, simply select the noun category, and you will see only nouns in the table.
The easiest way to set the word type, is to drag and drop a word onto its type. You can even do this with multiple words at the same time.
Use Add New Entry in the toolbar to add new words. You can start typing the word in the first language right away. By default Parley lets you enter another word when you press Enter in the last row, so you don't have to keep using the Add button. After entering the first word, press Tab to go to the next language.
If you want to replace a word, select its entry and start typing. To change the word instead, double click the entry and you can change the contents of the cell without losing the old word.
Press Tab to go to the next word. Enter leaves the editing mode. You can use the arrow keys to move around.
