The wordsouth comes fromOld Englishsūþ, from earlierProto-Germanic*sunþaz ("south"), possibly related to the sameProto-Indo-European root that the wordsun derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere),[1] like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', English:cf.meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name ofYemen, the land to the south/right of theLevant[2]).
