Could you also use a different word order:
יש ברוטב בצל
Yep. Works fine.
All right, then I'll have to report that next time.
Still marked wrong, two years later. I'll report it even though I don't get the sense that Duolingo is paying attention.
Could you say ברוטב יש בצל?
yesh batzál ba-rótev.
What about "בצל יש ברוטב" ? Would that order work?
