Syllable counts come from vowel tokens; CMUdict does not supply syllable boundaries here. Variant order follows the dictionary and does not rank correctness. This lexicon does not represent every accent or context.

Use phenomenon in context

Phenomenon names an observable event, occurrence, or fact that invites attention or explanation. Science lessons may use it for a physical effect, while cultural commentary may describe a popular movement. Narration should establish what the audience can observe before discussing the explanation or significance of that phenomenon.

The experiment demonstrates a phenomenon that appears when the liquid cools.
The documentary traces how a local dance became a worldwide phenomenon.

REVIEW CHECKLIST
[ ] Read both sentences naturally; keep the source wording.
[ ] Compare the intended pronunciation with the selected dictionary variant.
[ ] Listen for vowel sounds, consonants, and word stress in context.
[ ] Check with a speaker or another dictionary when accent or meaning matters.
[ ] Generate and listen to a short Murmur sample before exporting the full script.

Practice note: Test phenomenon near the description of the event it names. Listen to the whole explanation rather than isolating the word, and check singular and plural wording elsewhere in your script before recording a lesson that moves between several observations.
