Questions & Answers about Lijepu sam si pidžamu kupila.
What exactly does si mean here, and how is it different from the usual se?
si is the dative case of the reflexive pronoun, whereas se is the accusative case. In this sentence, si acts as a benefactive dative, meaning the action was done for the speaker's own benefit. It directly translates to "for myself."
Why are the adjective Lijepu and the noun pidžamu separated by other words?
This is a common feature in Croatian used to satisfy the strict "second position" rule for clitics (unstressed words like sam and si). Instead of starting with the full noun phrase (Lijepu pidžamu), the speaker splits it up, dropping the clitics immediately after the first word (Lijepu) to keep them in the correct grammatical position.
Could I change the order of the clitics and say Lijepu si sam pidžamu kupila?
No, the order of clitics in a cluster is strictly fixed. The auxiliary verb clitic (sam) must come before the dative pronoun clitic (si). The only exception to this ordering rule is the 3rd person singular auxiliary je, which always goes at the very end of a clitic cluster.
How do we know the speaker is a woman just from reading this sentence?
