"I have an orange plate."
Μετάφραση:Εγώ έχω ένα πορτοκαλί πιάτο.
I'm confused now. Maybe this sentence shouldn't be used in the skill about Food. I'll see if it can be changed. But in the meantime, to answer your question "Εγώ έχω ένα πορτοκαλί πιάτο" means that I have a plate that is the color orange. "Α plate with oranges" would be "ένα πιάτο με πορτοκάλια"
