"gorblflur" means "fan belt," so "gorbl" means fan and "flur" means belt.
"pixngorbl" means "ceiling fan," so "pixn" means ceiling and "gorbl" means fan.
"arthtusl" means "tile roof," so "arth" means tile and "tusl" means roof.
To form the word for "ceiling tile," we combine "pixn" (ceiling) from "pixngorbl" and "arth" (tile) from "arthtusl."
Thus, the word for "ceiling tile" is \( \text{pixnarth} \).
