Modifications

  • Excluded form-of entries and senses labeled archaic, dated, historical, obsolete, offensive, rare, slang or vulgar.
  • Selected only entries with complete standard present and past anchors, a past participle, and at least two Dutch examples with English translations.
  • Normalized whitespace, limited the number of displayed senses and examples, converted conjugation data into a compact table, and added A–Z navigation.
  • Kept separable forms as supplied in the source instead of mechanically inventing a joined form.
  • Added original speaking-retrieval instructions, evidence boundaries, product copy, page structure and internal links.
