How do you pronounce "de boom" in Dutch?

duh BOHM — a clean b, a long flat "oh," and a closing m.

de boom /də ˈboːm/

Both consonants are quick and soft, leaving the long vowel to carry everything. The plural "bomen" drops one o as the syllable opens — the same alternation as "boot/boten" and "zoon/zonen."

Sound it out

b A voiced stop released cleanly, with no breath following it.

oo Long and steady, held at one position for its full duration. English "boat" glides toward "oo" at the end; Dutch parks the tongue and stays.

m Lips fully closed at the end and held briefly, so the vowel stops rather than fading into nasalisation.

"Die boom is heel oud" opens with the demonstrative, correct because "boom" is a de-word. The adjective at the end carries the ou diphthong and a devoiced t, so the sentence moves from a long steady vowel to a gliding one.

Where English speakers slip

The English "boom" supplies the "oo" of "moon," which is the wrong vowel entirely — Dutch "oo" is an "oh." Learners also glide it on the English model. Both errors are about vowel quality rather than length, which makes them easy to miss when you are focused on getting the duration right.
