I thought language filters are built into Lemmy directly. Log in to your instance and you can see it there. I think the bigger problem is posts or communities need to be tagged with a language and most are defaulting to “unknown”, so if you filter for only English you’ll lose most of the communities out there.

Normally I would filter out other languages but… the non English speaking subs seem to be how I find out how a celebrity died. I don’t know any other word but I sure know what overleden means.

That plus trying to figure out what the German memes are trying to say almost fits as a daily puzzle.

(That being said it should be a feature if it’s not already)

I feel this should be a Lemmy capability and not client specific? I’d like to see it too - I feel like I’m somehow disrespecting all these interesting looking communities just because I can’t understand the language.
