People from Berlin have a distinctive dialect or accent, just like New Yorkers or Parisians.

As in some other German regional dialects (as opposed to proper Hochdeutsch), Berliners contract infinitive endings, losing the 'e' at the end of verbs: gehen -> gehn. Verbs conjugated into second-person singular also get contracted when used next to the 2nd-person singular pronoun: Hast du... ? -> Haste... ?.

Two notable consonant shifts occur in Berliner Dialekt. A word-final 's' often changes to a 't', as in was -> wat. Perhaps the most distinctive mark of a Berliner is his or her pronunciation of 'g', mostly in word-initial position: gut -> jut. (The 'j' is pronounced as in German ja.)

The most notable vowel change is in a diphthong: aufstehen -> uffstehen.

Berliners often mix up dative and accusative cases, especially with prepositions (mit, auf, etc.)
