Questions & Answers about Ana consultă catalogul.
Because Romanian usually puts the definite article at the end of the noun, not before it.
- catalog = catalog
- catalogul = the catalog
So -ul is the masculine singular definite article here.
Because consultă is a conjugated verb form, not the dictionary form.
- Dictionary form: a consulta = to consult
- consultă = he/she consults
In this sentence, it matches Ana, which is third person singular, so consultă means she consults.
