Translation of "harsh" into Bosnian

I know that sounds harsh, but it was very difficult, learning what she had been doing.

Znam da to zvuči oštro, ali bilo je vrlo teško kada sam saznala za sve.

The memory of your harsh words may have tormented her as she died.

Sjećanje na tvoje grube riječi možda su je mučile dok je umirala.

The steep terrain and harsh climate make a challenging climate for even the strongest of species.

Strmi teren i neprijatna klima predstavljaju izazov i za najjače vrste.
