Questions & Answers about Gingia sângerează.
Because Romanian usually puts the definite article at the end of the noun instead of using a separate word before it.
- gingie = gum / a gum
- gingia = the gum
So the -a at the end is the feminine singular definite article.
That is a very natural question. Romanian can use the singular when talking about gum tissue in a general or medical sense, so Gingia sângerează is possible.
But in everyday English, people often say my gums are bleeding, and Romanian often does the same with the plural:
- Îmi sângerează gingiile. = My gums are bleeding.
So the singular in your sentence is grammatical, but the plural is also very common depending on context.
