"Dah woozh"

Translation: Strawberry

[Tannuska]

I wrote Strawberries, and it was marked wrong. What is the plural for "Dah woozh"? I thought it would be used either for the singular or the plural! Please, clarify!

I'm writing in mid-august, 2020. Same story, Road strawberries.

Before I submitted, I checked the drop-down translations when I clicked on the target Navajo word (Dah woozh).

The drop-down options are strawberry, strawberries.

I'm a novice to the language, but it looks like out of context, it could be singular OR plural. Can someone correct me?
