we want a unified country (not an)
Yes, because the u in unified is a y sound.
I'm sorry for the (very) long delay. I made the changes.
really? "a unified country" is proper English.
The article a should be used if the following word starts or sounds with a consonant, a non silent h or a vowel pronounced [j] or [w]: unified
And so Vietnam was unified on 1975
"United" is not accepted
it was but just with "nation". for unknown reasons, only "unified country" and "united nation" were accepted. I made the changes.
"a unified", Not "an unified"
it has been corrected.
