More Esperanto tautologies, please.

[jcreed]

Vera vero vere veras.

[jax24]

I love how this is not only grammatically correct, but fun to say too.

[MickeytheGreat]

Does that mean true truth is truly true?

[Brauxljo]

I like "truthful truth is truly true"? Since none of the words are repeated.

[clh335763]

From a cursory internet search, "truthful" seems to be used much more frequently to refer to people who are truthful (eg. truthful witness), or the trait of telling the truth too (eg. truthful speech).
But I like how it sounds :) Have 2 lingots to show my sincere appreciation!

[diagnostuck]

And he delivers!

[Canvasian]

Tiu aparteni sur T-Cxemizo!

[jcreed]

Kaj sur la ĉemizo certe ankaŭ estos stelo, kaj pri steloj, ĉiuj scias ke la vera verda verdo vere, verde verdas.

La unua regulo de taŭtologia klubo estas la unua regulo de taŭtologia klubo. (Devenloko: https://xkcd.com/703/)

[Smalde]

Ho, mi forgesis "o"n

[gcdgfz]

I think this might have not been interpreted as a typo, because that is an actual english word too, which unfortunately doesn't fit in there.

[drxantiq]

It actually fits a lot

[maxkoryukov]

Thanks to your screenshot we can see how Duolingo changes over time;)

REALLY GOOD PERSON

[rapn21]

Makes sense

[ichteltelch]

Kapitano evidentulo batas denove!

[ThatOneDoge]

I saw it somewhere else as Evidenta. Is there a difference? Are both correct?

[ichteltelch]

I made up "evidentulo". It might be incorrect. But to me, "kapitano evidenta" sounds too much like "an obvoius captain".

[jax24]

Dankon, Duo. Mi ne sciis ĉi tiun.

[sf2k]

Awesome tautologies are awesome

[AjxojLerni]

well, i learned something today.

[blindcat97]

Akvo estas malseka! Fajro estas varmega!

[themuthafu]

Surprise surprise, who would have guessed that?

[jeo565932]

NOW I UNDERSTAND

[StanAwesome]

I dont understand why it's "ulo" instead of "persono" or "homo". Anyone care to clear this up for me?

[danielqsc]

"-ul-" is a suffix that means "a person characterised by what the root [before the suffix] expresses". Used alone, it means "a person" (since there's no root before it).

[Christophe251809]

Ŝajnas al mi mankas rekte anglan tradukon por la vorto "bonulo".

[RoboticBowtie]

can someone explain to me the usage of a comma in esperanto? it doesnt match up with how it sounds in english (atleast i dont think so? im a native speaker.)

[lumoso]

My understanding is that in Esperanto you put commas to separate just about any two clauses

[Jxefecxjo]

Akvo malsekas

[Merrowmic]

Ulino = female person, gal, bird?

[Trachurus1]

That should true (Majstro doesn't have ulino, though). What we need to know if ulo is only for males, or if it's gender neutral like amiko.

[Cavman144]

would "that" work in place of "who", here?

[phle70]

Yep, I just translated it as
A good person is a person that is good.
and got it marked as

You are correct
Another correct solution: A good person is a person who is good.

To quote the Swedish Chef, "Vert de Ferk?"

Brila depreno!

[KillioRocket]

This brings new levels to Department of Redundancy Department

[sbmassey]

Is there any difference in meaning between homo and ulo though?

[jjjosenaldo]

same energy as "katido estas ido de kato" in one of the first skills

[Vancow]

Goodfellas.

[sf2k]

I think of The Sphinx from Mystery Men

[SyntaXis1]

Can "bonulo" be translated as "white hat" and "malbonulo" as "black hat"?

[EsperantoHundo]

Perhaps in a special context.

[Erinacino]

Standing cat is standing

[zerozeroone]

Ceiling cat is ceiling?

[LiKenun]

Ceiling cat is sealing. :)

And taste good too. Didn't it? Esperantan fans?..

[aryabferduzi]

You don't say!

[PaulDeNice1]

Too convoluted for good learning. It reads like a mental "tongue twister" in Esperanto! I want to learn, not practice "double down" sentences at this stage of my learning - just a pain! Sorry for people who like this stuff! Lets have plain "learn the language examples"!
