In standard Dutch phonetic pronunciation, the preposition "van" is pronounced with a short, open vowel sound that closely resembles the English "vun," using a crisp "v" sound at the beginning and a soft, breathy "n" at the end. Unlike the English pronunciation of the word "van" (which rhymes with pan and uses a broad, flat vowel), the Dutch variant avoids any heavy nasal stretching and remains short and punchy. When native speakers use it inside a full sentence or a compound surname, it often undergoes a slight weakening into an unstressed schwa sound, making it blend smoothly before the main family identifier without heavy vocal emphasis.
