Definite and indefinite article
Slovak has no articles; there are neither definite nor indefinite articles. But if necessary we can use the demonstrative pronouns ten, tá, and to to function as definite articles. For indefinite articles, we can use the indefinite pronouns nejaký, nejaká, and nejaké.
