この歌を歌うのは難しいです

[AdonisCham1]

This is a tongue twister

[IdoAbelman]

Maybe it's a line in the song it describes

[NatoriErk]

"this song is hard to sing" should be accepted.

[JaredTafoya]

What's the difference between たいへん and むずかしい？

[boo913]

I'm not certain, but my intuition is that doing something that is たいへん requires great effort, while doing something that is むずかしい requires great skill.

[Anne624050]

That's about right.

むずかしい can also be translated to "difficult" or "complicated".

While learning a new language can be "たいへん" sometimes, a grammar point is not. But some of them are "むずかしい" nonetheless. ^^'

Why is it 'ha' here instead of 'ga'?

[James151779]

I thought basically that adding の after the verb was equivalent to adding "ing" to it. That is, changing "sing" to "singing"? But I put "It is hard singing this song" and was counted wrong - in favor of "It is hard to sing this song." Should both be correct? Or is my fundamental understanding out the window?

[Drunken_Sailor]

That the problem in to not study grammar. The
の after a verb turn the verb into a noun, so 食べる means "to eat" while 食べるの means something like "the act of eating" or just "eating". In some sentences it would be irrelevant but basically that's it.

[MaynardHogg]

"This song is hard to sing" also accepted.

[Kaleshe]

I wrote it is difficult to sing this song and it said it was wrong?

[Lorelai144]

Why does Duolingo almost never use kanji?

[Little_Tatws]

It does later on in the course. Especially on the 2.0 Tree.

[MaynardHogg]

It's a deliberately dumbing down. Teaching real Japanese with kanji (with furigana) would be too much like "teaching in context."

[MariannePl16]

why is "difficult" instead of hard not accepted???
