Is the word "didn't" one or two syllables?

[Zoli]

There is one vowel in it, however I'm not sure about the "n't" part which may have a vowel in it as well, a small schwa vowel, even though it is not shown in dictionaries.

I would think it should properly be two syllables, and Webster's shows both two and one syllable variations.

In real life, it is often sort of crushed into one syllable. You see this in slang writing on social media sometimes as "dint," which approximates the sound when the word is said rapidly. The second "d" is almost completely disappeared.

Where I live it's often compressed differently: by omitting the final t (two syllables still) .But we also say dint sometimes.

I teach beginner to upper-intermediate learners to say it with two syllables.

 

[Tarheel]

I suppose some people would say it as one syllable. People can sure be lazy.

U use two syllables.

Some BrE speakers use that too.
