Commentary

The word हैयंगवीन is anomalous when it is a Name.
The word हैयङ्गवीनम् means 'fresh butter'. The word comes from ह्यः 'yesterday' and गो 'cow'. ह्यो गोदोहस्य विकारः 'prepared from yesterday's milk' i.e. "fresh butter". The affix does not come in the sense of any विकार in general. There is no affixing in ह्यो गोदोहस्य विकार when it means उदश्चित् or 'whey'.
