"Am wn i"
Being asked to translate a phrase before being introduced to it and without hint menus has as much pedagogical value as being asked in which hand a pebble is being held.
Apologies but we have no control over when Duolingo throws phrases at users, there are not even any guidelines about this, I see that there were hints underneath the phrase, was there a problem with them not appearing?
No problem, really. I did not know that the questions were randomized. That, of course, explains why this happens from time to time. I was using my phone and this, the first question in the lesson, did not have hints. There were hints under the subsequent questions, though sometimes in the past I have had whole lessons without hints. I had thought it was a choice of the designers, but now I realize it is just my phone. Such things never occur on my computer.
They should be random on your computer as well ... it's the style of Duolingo to ask you to guess at things you don't know
It's from gwybod "to know" -- soft-mutated form of gwn which is the formal form for "I know".
I'm pretty sure it is. (I also hear the abbreviated version of that, dwn i'm.)
I was interested to read about hints - where are they? I use a Mac so maybe I don't get them
At the top of this page, the Welsh sentence Am wn i has a dotted line underneath the words.
When I move the mouse over a word and let it rest over the word (without clicking), a little window pops up with some meanings for that word, sometimes also for that word in combination with other words near it. Those are the hints.
