What is the superlative form of "often"?

most often ?

I'm not 100% sure but if i can remember i believe that the superlative of often is:
amoftesten (the o has the two dots on top)

because the comparative would be:
ofter (with the o having the two dots on top)

if you mean in german: am öftesten

Most often would be the superlative form

You are close, but the correct superlative form of "often" is actually "most often." So, your initial assumption was right.

To form the superlative form of adverbs, like "often," in English, we generally add the word "most" before the adverb. So, "often" becomes "most often" in the superlative form.

In German, as you mentioned, the superlative form of "often" is "am öftesten."

Remember, superlative forms are used when comparing three or more things, so we use the superlative form to describe the highest degree or intensity of something.
