"Thank you!"

Translation: Děkuji!

[LendMeName]

Difference between Dekuji and Dekuju?

[VladaFu]

It is the same, but Děkuji is more formal.

I can not type accents.

Are you on a mobile device? They may not be easily available. I am using a desktop computer and below the answer box, I see, and can click on, all of the letters that have accents. Supposedly you can type them directly if you are by using your keyboard shortcuts but I haven't been able to get that to work on my computer. I may need to add something to my browser to use the shortcuts like CTRL Shift ^ c to get the ĉ.

A very tedious method is to create a document with all of the accented letters in it. Leave it open and copy and paste from it when you need one. If I use an accented letter a lot, such as the ý, I just keep it in my "paste" buffer.

I hope this helps you!

On a mobile device it is very easy to install a virtual keyboard for any language. https://forum.duolingo.com/comment/35321961/I-can-t-type-the-accents
