This software, LingvoSoft Dictionary English Portuguese for Palm OS, has a database of 400,000 words and offers bidirectional translation with instant back translations. It also features Quick Search, Vector Ultima spell-checker, and other convenient search functions.

One of the great features of this dictionary is its ability to provide immediate back translations. If you come across an unfamiliar word while working with another application, simply highlight and copy the word, then launch your LingvoSoft dictionary. At start-up, the word will be automatically picked up from the clipboard and pasted into the dictionary.
Searching for words is made easy with Quick Search, Vector Ultima spell-checker, and the signature MorphoFinder functions. Each dictionary entry is completed with part-of-speech information, and several translation options are offered for all polysemantic words.
The software's word databases, attractive fonts, and original keyboards make LingvoSoft dictionaries nothing but pleasure in use. With its numerous features, this software provides a comprehensive dictionary that is perfect for those learning a new language.
Some of the dictionary's highlights include an overview of all dictionary entries in the Main List, an overview of all possible translations of a selected word in the Translations List, quick back translation for proof of correct understanding, and a quick search function that displays entries starting with such letter combinations.
Switching between languages is easy and can be done by simply tapping the pop-up trigger in the upper right corner, which changes the direction of translation. The MorphoFinder function helps to find source words (headwords) for past participles, gerunds, and plural forms. Additionally, there is a spellchecker for both languages, high-resolution support, and SD/MMC standard support.
You can store applications and/or databases on an extension card (SD/MMC) and run the application from the main memory or the extension card, regardless of where the database is located. All in all, the LingvoSoft Dictionary for English and Portuguese is a must-have for anyone looking to communicate effectively in both languages.
