Learn Croatian: Tišina je ovdje beskompromisna. - The silence here is uncompromising.

The prefix is bez- (meaning without). However, because the root word kompromis starts with the voiceless consonant k, the voiced z at the end of the prefix changes to its voiceless pair s. This process is called voicing assimilation and it makes the compound word easier to pronounce.

How is the feminine adjective ending applied to this compound word?

The base masculine adjective is beskompromisan. To make it agree with the feminine noun tišina, we add the feminine ending -a. Because of the fleeting a rule you learned earlier, the a before the n drops out in the feminine form, leaving us with beskompromisna.

Could I change the word order to emphasize the location, like Ovdje je tišina beskompromisna?

Yes, but you must pay attention to the enclitic je. It needs to sit in the second logical position of the sentence. Ovdje je tišina beskompromisna is perfectly correct and shifts the focus to the location, whereas the original sentence makes the silence itself the main topic.

Can beskompromisna describe people as well as abstract things like silence?

Absolutely. Just like in English, it can describe a person who refuses to make concessions. Depending on context, it can be a positive trait (principled) or a negative one (stubborn). In this sentence, it is used metaphorically to mean the silence is absolute and unbroken.
