Questions & Answers about Projekcijsko platno stoji između ulaza i izlaza.
Because the adjective has to agree with the noun in gender, number, and case.
Here, platno is a neuter singular noun, so the adjective must also be neuter singular:
- projekcijski = masculine
- projekcijska = feminine
- projekcijsko = neuter
So:
- projekcijsko platno = projection screen
This is the normal agreement pattern in Croatian.
Platno literally means cloth, canvas, or screen, depending on context.
In this sentence, projekcijsko platno means a projection screen or movie screen.
So even though platno can mean fabric in other contexts, here it clearly refers to the screen used for projecting images.
