1. Type the word you want to search for in the box located in the central area and click on the Search button.

2. A window will open that allows you to select the word in a particular language.

3. Once the word is chosen, you will have access to the tree graph, where your word appears highlighted in bold, and you are shown the direct descendants in the same language (derived and compound words) and its direct antecedents in another language. Next to each word is a figure: a circle, a square, or a pentagon. Each figure has the colour of the language to which the word corresponds, given that languages are in different colours. You can click on the figures that have an arrow to display more descendants.

The circles indicate that the associated word only has a base in its own language. You can click on the word with square or pentagon.

The pentagons indicate that the associated word has both a base in its own language and an antecedent in another language (an origin). By passing the mouse over the word, the symbol hand appears: click on it and the links with its base (solid line) and with its origin (dashed line) appear.

The squares indicate that the associated word has more than one base in its own language (two, as a general rule). Click on the word, and the graph corresponding to its two bases appears.

Branches in solid lines indicate derivative relationships between words of the same language, while branches in dashed lines indicate relationships between words from different languages.

By moving the mouse over the word, a small window opens with specific information about that word: type of unit, grammatical category, morphological meaning, type of process, affix, etc.

Use the mouse wheel over the graph to increase or decrease its size.

Press and hold the mouse button to move the graph.

Click on the figures with an arrow to show/hide their descendants or derivatives.

Click on words with gray-edged circles to show all their derivatives.

Move the cursor over words to show additional information.

Use the options button filters to select the nodes that you want to view in the graph.
