Onko Punainenmeri oikeasti punainen?
"Red Sea" is a direct translation of the Greek "Erythra Thalassa" (), Latin "Mare Rubrum" (alternatively "Sinus Arabicus", literally "Arabian Gulf"), (alternatively بحر القلزم "Baḥr Al-Qulzum", literally "the Sea of Clysma"), Somali "Badda Cas" and Tigrinya "Qeyyiḥ bāḥrī" (ቀይሕ ባሕሪ). The name of the sea may signify the seasonal blooms of the red-coloured "Trichodesmium erythraeum" near the water's surface. A theory favoured by some modern scholars is that the name "red" is referring to the direction south, just as the Black Sea's name may refer to north. The basis of this theory is that some Asiatic languages used colour words to refer to the cardinal directions. Herodotus on one occasion uses Red Sea and Southern Sea interchangeably.
