[Middle English, from Old English sūth; see sāwel- in the Appendix of Indo-European roots.]
Word History: When observed from the ground in the Northern Hemisphere, the path that the sun travels in the daytime lies generally in the southern half of the sky. For this reason, the sunny side of a hill or a house in the Northern Hemisphere is the south side, and this fact about the sun is reflected in the origin of the English word "south" itself. "South" in Old English was sūth, which developed from an earlier *sunth. (As Old English developed from its Germanic ancestor, an *n within a word was dropped before the sound *th, and the preceding vowel was lengthened in compensation.) The form *sunth developed from a still earlier Germanic *sunthaz, literally meaning something like "sunny, besunned," and the first element in this word, *sun-, means "sun." The same element can also still be found in Modern English sun, from Old English sunne. As the first word in compounds, Old English sūth, "south," was subject to shortening, and it shows up in Modern English pronounced (sŭ). This is seen in place names like Suffolk (where the "south folk" were; compare Norfolk), Sutton, "south town," and Sussex, the location of the "South Saxons" (whose eastern and western cousins were located in Essex and Wessex, respectively).
