Questions & Answers about Lončarsko kolo radi polako.

Why does lončarsko end in -o?

Because it agrees with kolo, which is a neuter singular noun.

In Croatian, adjectives change their endings to match the noun’s:

• gender
• number
• case

Here:

• kolo = neuter singular
• so the adjective is lončarsko = neuter singular nominative

That is why you get:

• lončarsko kolo = potter’s wheel

If the noun were masculine or feminine, the adjective would change:

• lončarski ... for masculine
• lončarska ... for feminine
• lončarsko ... for neuter
