Learn Romanian: Femeia este aici.

In Romanian, the word for "the" is attached to the end of the noun. The basic dictionary word for "woman" is femeie. Because it is a feminine noun ending in -e, we drop that final -e and add -a to mean "the". Therefore, femeie becomes femeia.

I have learned that words ending in -ă or -a are usually feminine. Is that why femeia ends in -a?

Yes and no! While it is a feminine word, the base noun is femeie, which ends in -e (another common ending for feminine nouns). The -a at the very end of femeia is specifically the attached definite article meaning "the", not just the basic shape of the word.

How do you pronounce the end of femeia?

The ending -ia blends together to sound like "ya" in English. You do not pronounce the i and a as two completely separate vowels. The whole word is pronounced roughly like fe-ME-ya.

Could I say e instead of este in this sentence?

Yes, absolutely! The word este is the standard, full word for "is". However, in everyday spoken Romanian, people very often shorten it to e. Saying Femeia e aici is perfectly natural and means exactly the same thing.
