Learn Swedish: Vi såg både föreläsningen och panelen här tidigare. - We saw both the lecture and the panel here earlier.

This showcases the Swedish "Place before Time" rule, often called the "Rum-Tid" (Room-Time) rule. When you have multiple adverbials at the end of a sentence, Swedish strictly places the location (här) before the time (tidigare). While English is sometimes flexible, Swedish is very consistent about this order.

How do you use både ... och ... in a sentence like this?

The phrase både ... och ... translates directly to "both ... and ...". It is a paired conjunction used to link two things together, just like in English. Here, it connects the two events you saw: både föreläsningen (both the lecture) och panelen (and the panel).

Why do föreläsningen and panelen both end with -en?

That ending is the definite article, which means "the". Instead of putting a separate word for "the" in front of the word, Swedish attaches it to the end of the noun. So en föreläsning (a lecture) becomes föreläsningen (the lecture), and en panel (a panel) becomes panelen (the panel).
