"Quyển từ điển"
I wrote quyển từ điện. On many lessons, when I mistype, it accepts it, but shows me the correct sentence with the word I had the wrong accent on, underlined for emphasis. Here it just accepted what I wrote without any correction. I've noticed lately this happening often. I'm not sure why, but it is really helpful to be alerted when I put the wrong tone, or at a letter wrong (another example: yesterday I wrong a word as tiêng that was accepted without telling me it was mistyped, when it really should have been tiên).
