Questions & Answers about Kupujem taj skupi parfem.
Why is the verb kupujem used here instead of kupim?
Kupujem comes from the imperfective verb kupovati, which is used for ongoing or continuous actions, equivalent to the English present continuous (I am buying). Kupim comes from the perfective verb kupiti, which focuses on a completed action and is rarely used as a standalone present tense verb, except in specific subordinate clauses or habitual contexts.
Why does the adjective end with an -i (skupi) instead of being in its short form (skup)?
In Croatian, masculine adjectives have definite (skupi) and indefinite (skup) forms. Whenever a masculine adjective is preceded by a demonstrative pronoun like taj (that) or ovaj (this), you must use the definite form. It signifies a specific, known object.
Since taj skupi parfem is the direct object, why doesn't it take accusative endings like -og and -a?
Parfem is a masculine inanimate noun, meaning it is not a living being. For masculine inanimate nouns, the accusative case looks exactly the same as the nominative case. If you were buying an animate object, like a dog (pas), the endings would change to the animate accusative form: Kupujem tog skupog psa.
