"Cos'è" is what is; while "Che cos'è" is what is it/that (direct translation of "che cos'è" is "that what is".. I hope you understand it.

I'm confused too. I thought "Cos'è" meant "What is it?"

Che é was also given as correct?

Essentially you're saying, "what there is". C'è is the contraction of "ci" and "è" which means "there is". "Cosa" is used with "che" but it's not exclusive to it and it essentially means "what thing".

I vouche as well. I just saw DL translate "Cosa c'è" as "What is it?" in a question right before this one. I paid special attention, because I missed this current question already and thought I'd seen the prior one--so I was confused as to how I got this wrong.

I just added it as a possibility. They do have different meanings, however, and are used in different contexts. "Cosa c'è?" (And "Che c'è?") means "What is it?" as in "What's wrong?" "Cos'è?" (and also "Che cos'è" and "Che è") means "What is it?" as in "What is this thing?"

"Che cosa" = "what".

Hello SMCanlis! "chi" means "who", "che" means "that"

What is "che", then you put the subject "Cosa", which is completed by a verb "è".

Dunno, cos'è is more direct, not so much more polite than "che cos'è". But it is the sane thing! (I'm Italian)

On a tablet, as on a mobile phone, is you long press the letter in question you will normally get a pop up window offering that letter with different types of accents; I get it in Android.

Both, but DL should accept it as a typo unless something changed. 'Ché' has the meaning of 'perché' (because/as/since) instead of 'che' (that/what/which/whom/...), and in Italian orthography you don't put a space before punctuation.
