LingvoSoft Dictionary Spanish Russian for Palm OS contains a 400,000-word database that translates in both directions and offers quick searching using Quick Search and Vector Ultima spell-checker. It also provides instant back translations.

Searching is made easy with Quick Search, Vector Ultima spell-checker, and MorphoFinder functions. Each entry in the dictionary is completed with part of speech information, and multiple translation options are offered for all polysemantic words.
The software features an overview of all dictionary entries in the Main List and all possible translations of a selected word in the Translations List. A Quick back translation function ensures that you have correctly understood the word you're searching for. The Quick search function allows you to type in a word into the Input Line, and entries with matching letter combinations will be displayed.
Switching between languages is easy - simply tap the pop-up trigger in the upper right corner, and the direction of translation will change. The MorphoFinder function helps find source words (headwords) for past participles, gerunds, plural forms. The software also includes a spellchecker for both languages and supports high-resolution displays.
SD/MMC standard support allows you to store applications and/or databases on an extension card. You can run the application from the main memory or extension card, regardless of where the database is located. The attractive fonts and original keyboards combined with splendid word databases make LingvoSoft dictionaries nothing but a pleasure to use. Enjoy this powerful translation tool for your Palm OS device.
