"A népszerű énekesnő fellép a városban."

Translation: The popular singer is performing in the city.

[BetsyLowe]

Is fellép related to fel+lép, as in stepping up somehow?

[RyagonIV]

Yes, good catch. I can also offer you the German "auftreten", which has the same literal and figurative meanings. You can imagine it like stepping onto the stage/scene (szín in Hungarian, easy to remember).

[JustCallMeJay]

I imagine that during the Hungarian language reformation in the 18th and 19th centuries, Hungarians formed many words from German calques.

[GerSzej]

I do not understand why "female" singer is still rejected. reported
