S is the nineteenth letter in the modern Latin alphabet. Its name in English is ess, or es- in compounds such as es-hook.

In most writing systems that use the Latin alphabet, as well as the International Phonetic Alphabet, the letter [s] corresponds to a voiceless alveolar sibilant.

Semitic Šîn (šimš sun/uraeus) was pronounced as the voiceless postalveolar fricative [ʃ] (like the sound of the letters sh in ship). Greek did not have this sound, so the Greek sigma (Σ) came to represent [s]. The name "sigma" probably comes from the Semitic letter "Sâmek" (fish; spine) and not "Šîn". In Etruscan and Latin, the [s] value was maintained, and only in modern languages has the letter been used to represent other sounds, such as voiceless postalveolar fricative [ʃ] in Hungarian or the voiced alveolar fricative [z] in English, French and German (in English rise; in French lisez (="read" imperative plural); in German lesen (="to read").

Care must be taken for incompletely anglicized words from German and proper names from that language. The trigraph "sch" is pronounced similarly to the English digraph "sh," though with rounded lips. When starting a word, but followed by a consonant, it is pronounced with the same "sh" sound (e.g., smuck, snell, spitz), but when starting a word followed by a vowel, it is pronounced like the English "z," not the German one. Firms started in German-speaking countries, like Siemens, would prefer to have their customers world-wide pronounce the name of the company in this manner.

An alternative form of s, ſ, called the long s or medial s, was used at the beginning or in the middle of the word; the modern form, the short or terminal s, was used at the end of the word. For example, "sinfulness" is rendered as "ſinfulneſs" using the long s. The use of the long s died out by the beginning of the 19th century, largely to prevent confusion with the minuscule f. The ligature of ſs (or ſz) became the German ess-tsett ( ß ).
