"Aren't you a musician? Yes."
Translation:Nach e neach-ciùil a th' annad? 'S e.
I had this as a "Write this in Scottish Gaelic" question and answered using the tiles provided. I was told "You have a typo." with the correct answer being given as "Nach e neach-ciùil a th' annad? 'S e." with th' underlined. However, the best available tile was th with no apostrophe. I have reported this as "Something else went wrong."
The Duolingo software is inconsistent in ways it handles some punctuation (apostrophes in this case) – it ignores it completely in some cases (like in the tiles, not giving you tiles with apostrophes at words boundaries) but requires them in answers. It’s a common problem and I don’t think the Scottish Gaelic contributors can do anything about it without the help of the Duolingo staff.
I encountered the same problem although there was no underlining. When the same question came up again, I tried "neach ciùil" without the hyphen, and was marked correct! Incidentally I had reported the first attempt as "should have been accepted", so it should come to the attention of the Duolingo people.
Commenting under sentence discussions – which are not read by Duolingo staff, the only people who can do anything about it – won’t help.
