"Those English gentlemen don't ever speak in Spanish."

It's not wrong!

agree. further why tipos for senores ( as duolingo 's answer indicates)

I wrote "aquellos" too. It is still marked as wrong, which it is not. I reported it as "my answer should be excepted".

Hi. Do you know how to form the "tilde" with your keyboard? Whether using a laptop or connected by mobile device, a person can change their keyboard to a Spanish one.

""señores""
""español""

As an aside...

I learned that ""no nunca"" (together, like that) translates into ""never ever"", in English.

So, the following sentence is what we get:

• ""Aquellos señores ingleses no nunca hablan en español.""

  ""Those English gentlemen never ever speak in Spanish.""

NOTE:
""...no hablan nunca"" translates into...

""...[they] never speak""

I had another mistake in my sentence, but Duo accepted caballeros.

A relative of mine (a man) was writing (in Spanish) to a woman, recently, and she paid him a compliment by writing back and saying...

"Eres un buen caballero."
(You are a good gentleman.)

No idea, its annoying because my teacher says caballeros is gentlemen and señores is sirs.

Because Estos means These and Esos means Those.

I often get an answer wrong because I got estos/esos or estas/esas mixed up again ... and again. I know better if I really think about it, but I still often do those wrong. But I know that I didn't make a typo, that I really did translate it incorrectly, so I know that Duolingo was right to mark me wrong and correct me.
