How do you pronounce brain in Arabic?
"Triangle" in Arabic, is "mosallas," MO-SAL-AS. The word for triangle in Proper Arabic is: Mothalath (مثلث). In many dialects, however, people does not pronounce the "th" sound like in "thin", so they replace it with an "s" sound, like above. This, however, is not proper. (It's the same way that some Americans pronounce "Thity-three" as "Tirty-tree".)
