In modern typefaces, lowercase stigma is similar in appearance to final sigma (ς), but the top loop tends to be larger, and extends farther to the right. In modern practice, the term stigma is often applied to the symbol ϛ both in its function as a ligature and as a numeral, whereas the term digamma is normally used for the ancient letter representing /w/, which appears in modern print as Ϝ or ϝ (the form has a large number of close variants). The association between the numeral 6 and the letter sequence στ became so strong that today, in Greece, the letter sequence ΣΤʹ or στʹ is often used in lieu of ϛʹ itself to write the number 6. It was conflated with the στ ligature owing to the accidental similarities of their shapes. Originally called wau, it was called digamma in classical Greek and episemon during the Byzantine era. In its handwritten forms, its shape changed from through to or during the Hellenistic period and late antiquity. This symbol became obsolete as a letter during the classical era but remained part of the Greek alphabet-based system of numerals, where its value of 6 corresponded to its original place in the alphabet. The numeral symbol, originally quite unrelated to the στ ligature, developed from the letter Ϝ, which stood for the sound /w/ in early pre-classical forms of the Greek alphabet.

Stigma was co-opted as a name specifically for the στ sign, evidently because of the acrophonic value of its initial st- as well as the analogy with the name of sigma.

The name, stigma ( στίγμα), is originally a common Greek noun meaning "a mark, dot, puncture", or generally "a sign", from the verb στίζω ("(I) puncture") the related but distinct word stigme ( στιγμή) is the classical and post-classical word for "geometric point punctuation mark". The στ ligature was among the last to go, around the middle of the 19th century. Between the 18th and 19th centuries, the use of ligatures in print gradually diminished. With many other ligatures, it was used to print Greek during the early-modern era. It is based on the lunate form (Ϲ) of the letter sigma. The στ ligature (, ) was one of many ligature forms that came into widespread use as part of the minuscule writing style of Greek from the 9th and 10th centuries onwards. In this unrelated function, it is a continuation of the old letter digamma (originally Ϝ, cursive form ), which had served as a numeral since antiquity and was conflated with the σ-τ ligature in the minuscule handwriting of the Middle Ages. It is also used as a numeral symbol for the number 6. Right now SIGMA believes the actions the federal government has taken to be sufficient.Stigma ( ϛ) is a ligature of the Greek letters sigma (Σ) and tau (Τ), which was used in writing Greek between the Middle Ages and the 19th century. We hope that through these actions, when the time is right, they will bring a chapter back to SDSU and be productive members of our community. There is no place in our campus community for the type of ongoing behaviors displayed by those involved with this fraternity chapter, we appreciate the willingness of the national office of Delta Sigma Phi to step in and address these issues and take action with us. And I've done a show actually at Oklahoma last year, so to see that that chapter feels that type of way toward the black race, it hurts, man. These fraternities are places that us as hip-hop artists, we come and do amazing shows for these fraternities, like I just did Texas Tech, I just did Texas AM, Delta Chi, Sigma Chi, and those guys were great.

The commitments offered by the companies address these concerns.Īllowing drivers to occasionally work more hours will reduce the number of trucks and drivers it takes to move the same amount of fuel, right now SIGMA believes the actions the federal government has taken to be sufficient. The decision is conditional on the divestment of certain Sigma-Aldrich assets, including manufacturing assets in Germany, the rights to certain brands and a sales force, the Commission had concerns that the merged entity would have faced insufficient competitive pressure from the remaining players in the markets for certain laboratory chemicals, with a risk of price rises.
