Don’t remember a lot of it, but we were taught a new verb — senden (to send)
Similar to what we’ve seen in the past, the S is pronounced like a Z since it comes in the beginning of the sentence. We saw this with singen (to sing) as well. Another thing to keep in mind here is that this pronunciation change only happens when the S is followed by a vowel. An anti-example would be schlafen (to sleep) where there is no Z sound.
Then, we learned about Übermorgen (day after tomorrow). We were already familiar with morgen, and the uber- prefix simply means over or after or above. Prefixes like this are present heavily throughout the vocabulary, just like the ver- prefix, of which we were made aware of in lesson 9.
