"Gray pants and white shirt" should have been accepted. There's nothing about "kemeja" that indicates it's explicitly plural in this context.
Fun fact, if anyone's interested: "abu-abu" comes from the word "abu", which means "ash"
So if I want to say "we have different kind of ashes" how do plural the word ash/"abu"?
The plural form of abu (ash) is abu, not abu-abu.
Make sure that the variant spelling "grey" (i.e. non-US English) is also accepted in the free-text response.
How do you know if shirts is singular or plural? Either should be correct.
In this context, Abu-abu doesn't mean Grey in a plural form, it simply means: Grey colour.
singular shirt, not shirts
What's the difference between ''abu'' and ''abu-abu''?
Colours can't be plurals... right?
"Abu-abu" isn't the plural of "abu"; they're separate words (one is derived from the other). "Abu" means "ash", and "abu-abu" means "grey"
Why shirts - plural? Should be shirt, not shirts
