I must disagree. It's accurate that the word "webtoon" can refer to Chinese webtoons as well – but "webtoon" is what is used to refer to digital publication + the style of panel layout designed to be swiped vertically on a screen. "Manhwa" predate and extend beyond this (https://en.wikipedia.org/wiki/Goong_(manhwa) and https://en.wikipedia.org/wiki/Full_House_(manhwa) are two that got big and were adapted to hell and back) being the general term for Korean comics – which, in the print era, had the typical print layout. I think it's worthwhile to be precise in these conversations because there are Japanese webtoons as well these days, which would properly constitute "manga" as well, and if we're mixing up all the "comics" words from different languages with the trends in their formats, it's going to be a pain to discuss.
