How to Say ‘I should know’ in German

Ich wissen soll

ikh VIS-sen zoll

[ikh VIS-sen zoll]

💬 Usage Tip: This sounds incomplete on its own. Standard German would be ich wissen sollte or, in a clause, ich wissen soll. Fun grammar alert: soll = am supposed to/should.

🇩🇪 In Germany: In everyday German, people often shorten sentences in speech, but in writing full grammar matters more.

Berlin bureaucracy requires real German. This app got me from zero to handling my Anmeldung appointment in three weeks. My coworkers couldn’t believe it.

Relocated to Munich with my family. The everyday scenarios — grocery shopping, doctor visits, school meetings — are exactly what we needed to settle in.
