"usturoi"

Translation: garlic

[ChrisVossen]

So is this the same for single as plural?

[MihaiHe]

Yes, according to this site https://dexonline.ro/definitie/usturoi/paradigma
We also use the expression "cățel de usturoi" which means clove of garlic, with the plural "căței de usturoi."

This is a funny expression because usually "cățel" means little dog or puppy.

[JamesTWils]

Another uncountable. Cloves or heads of garlic, if you mean quantity.
