"Please give me a white blouse."
Are you using a PC? In the bottom right corner it shows your default language, you can add other keyboards by clicking it. Then on the lesson you can choose if you wanna use the usual tiles or type the answer yourself.
I explained phones in another topic: https://www.duolingo.com/comment/23986114 (but I haven't seen a type in lesson on my phone yet)
Is that what you meant?
