Here is the fix for Joomla 2.5xx

1. Click Extensions > Language Manager > Overrides
2. Click "New" button
3. Enter JGLOBAL_ARTICLES in the search box and check the "Language Constant" radio
4. Once the constant is found, click on it to pop it into the Language Constant on the left side of the screen - you'll see the word Articles appear in the text box below
5. Remove this text and leave it blank
6. Save

Voila!
