"A stage"

[gpbalis]

ενα σταδιο is also correct and should be accepted for " a stage" This doesn't have to mean a stage in a theater. It could mean a stage in developement
I reported it but it cost me a heart

Yes, and thank you again. I've added it in as alternative along with "φαση" which it brought to mind.

I made a error in this answer, and the correction wasn't in Greek, but in English, "skini", which I wasn't expecting.

The correct answer, as shown above, is Μία (Μια) σκηνή, ΜΙα (Μια) εξέδρα or Μία (Μια) φάση]. At one time we accepted "Greeklish" that is Greek using Latin letters (skini) but it is no longer accepted. The Duobot has an error.

Thank you for explaining, Jaye!
