Segments presented in the table above were automatically extracted from PIE roots with matching anlauts taking into account the formal semantic match among their glosses or glosses of cognates from the daughter languages provided in English, German, French, or/and Russian (all strings of symbols in single quotes, e.g. 'go', are automatically compared as glosses). These segments are conventially called "extensions", although each case if a matter for thorough analysis.

Each segment is provided with a link to the roots from which it has been extracted.
