I am concerned that the Duo team is adding alternatives that are not good English without proper vetting. And I personally do not consider a Google search for frequency as proper vetting. This "seldomer" issue is not the only example I have seen. Yes, I know we are not teaching English here, but there is no reason to add poor English to the list of correct choices just because someone suggests it. I gather that there are non-native speakers of English here learning Polish also, and I don't think we should be reinforcing poor English.

For my tuppence worth:

[frandogk3]

More seldom, and especially seldomer are not correct English.

[zagadka314]

it depends on your dialect. I think most Americans would see "more seldom" as perfectly natural and correct. It is even part of a phrase: "More seldom than not." But for what it's worth, I believe that one originated in a Bush speech…

What is wrong with "I am running less often than her husband."?

[Jellei]

I don't think Continous "am running" matches the word "often"...

[frandogk3]

But "less often" is a MUCH better way to say "more seldom".

[palitwin]

I am running and I go running can mean the same thing in English. "I am running" does not necessarily mean continuously. It would be quite proper to say in English, "I am running everyday" without implying that I never stop.

[frandogk3]

That is perfectly fine English, and implies that the habit of running for exercise is continuous, not that the running itself never stops.

[zagadka314]

That doesn't sound right to me. Where are you from?

[palitwin]

The USA

[zagadka314]

Me too. What part?

[Walkinthedog]

Interesting comments, I also had run less and your explanation makes your point valid. The problem is in the states, depending on where you live, everyone has their regional dialect and way of expressing them selves. I believe there are few languages that are as fluid as English and as such a certain criteria must must be met for stability. Of course that's only my opinion.

[pdamerval]

I don't quite understand why I can't say "I run more rarely than her husband does". It is quite acceptable English.

[Jellei]

"more rarely" works, it was "does" that was a problem, added now.

[Hot-Doggy]

What about "Biegam mniej częściej niż jej mąż"? That's what I would have said before Duolingo! Is it correct or am I way off the mark?

[alik1989]

Mniej and częściej are both comparatives, so you'd be basically saying "less more often".

Technically, "mniej często" would be grammatical, however, a language corpus search revealed that it's used about a thousand times less often than "rzadziej" and it also doesn't sound natural to me in this particular context.

[Hot-Doggy]

Thanks for clarifying. Thanks also for your comments regarding "mniej często" — that would have been my next question!

You've killed two birds with one stone! Cheers! :)
