<p>The Macro-Etymological Analyzer is a free, open-source tool for etymological analysis of plain-text documents. Users can upload their own file, or choose from a list of pre-loaded texts. The tool conducts a frequency analysis and then identifies the language families represented in the text from the list of unique words. It outputs a chart showing the percentage of words belonging to each language family identified, a full list of words with those not in the dictionary clearly marked, and a table outputting the full freqency analysis results.</p>
