Andererseits ist nicht zu vernachlässigen

Place Andererseits at the very beginning of your sentence. Because of German word order, the verb ist must come next. Then, add nicht zu vernachlässigen. Finally, state the thing you shouldn't forget. It sounds very professional and structured. You can also use it in the middle of a long sentence if you're feeling fancy.

Use it when you want to sound intelligent. It’s perfect for office meetings or academic essays. Use it when discussing big life decisions with friends. It works well when you are weighing pros and cons. It shows you are looking at the whole picture. It’s a staple for anyone aiming for a C1 level of fluency.

Avoid this phrase in a loud, messy bar. It’s too formal for shouting over music. Don't use it for tiny, unimportant details. If you're just picking a movie, it might sound a bit dramatic. Keep it for things that actually have some weight or consequence.

Germans love a good, deep discussion. There is a cultural value placed on being gründlich (thorough). This phrase reflects that need to be precise. It’s not just about winning an argument. It’s about finding the most logical conclusion. It’s a hallmark of high-level German rhetoric and the famous Streitkultur.

You will often see it paired with Einerseits. Together they form the "On the one hand... on the other hand" structure. You can also say Des Weiteren ist zu bedenken. Or simply Man darf nicht vergessen. All of these help you build a solid case while sounding like a local expert.
