I am surprised from that. vs. I am surprised by that.

When we want to say that something causes our surprise, we use the preposition “by” after “surprised” in English.

Czech learners often say “surprised from” because in Czech we say „jsem překvapený z něčeho“, což by se dalo doslovně přeložit jako “surprised from something”. But in English, the correct preposition here is “by”.

Here’s a short conversation using the correct phrase:

A: I am surprised by the news.
B: Me too! I didn’t expect that.
