Microsoft has started rolling out Language Interface Packs for its latest Office suite. A total of 62 Language Interface Packs (LIPs) will be available to download in coming days. Basque, Catalan, Galician and Serbian Cyrillic LIPs are available to download as of now.
LIP is a translated user interface that installs on top of a copy of Microsoft Office 2010. The LIP can be downloaded and installed for free and includes spell checkers in these languages.
Once the LIP is installed and configured, you can change the user interface for Microsoft Excel, OneNote, Outlook, PowerPoint and Word to your LIP language and use the spell checker in the language.
