Mora (plural moras or morae) is a unit in phonology that determines syllable weight, which in some languages determines stress or timing. As with many technical linguistic terms, the definition of a mora varies. Perhaps the most succinct working definition was provided by the American linguist James D. McCawley in 1968: a mora is “Something of which a long syllable consists of two and a short syllable consists of one.” The term comes from the Latin word for “linger, delay”, which was also used to translate the Greek word chronos (time) in its metrical sense.

A syllable containing one mora is said to be monomoraic; a syllable with two moras is said to be bimoraic. Also, in rarer cases, a syllable with three moras is said to be trimoraic.

In general, moras are formed as follows:

In general, monomoraic syllables are said to be light syllables, bimoraic syllables are said to be heavy syllables, and trimoraic syllables (in languages that have them) are said to be superheavy syllables. Most linguists believe that no language uses syllables containing four or more moras.

DeAndre Cortez Way (born July 28, 1990), better known by his stage name Soulja Boy Tell 'Em, or simply Soulja Boy, is an American rapper, record producer, actor, and entrepreneur.

In September 2007, his single "Crank That (Soulja Boy)" reached number one on the Billboard Hot 100. The single was initially self-published on the internet, and it later became a number-one hit in the United States for seven non-consecutive weeks starting in September 2007. On August 17 Way was listed at #18 on the Forbes list of Hip-Hop Cash Kings of 2010 earning $7 million for that year.

Way has currently released three studio albums and one independent album: his debut studio album Souljaboytellem.com (2007) was certified platinum by the RIAA. However, his next two albums, iSouljaBoyTellem (2008) and The DeAndre Way (2010) did not match the commercial success of his debut, the latter only selling 100,000 copies, despite the success of several singles across both albums, such as "Kiss Me Thru the Phone" and "Turn My Swag On" (iSouljaBoyTellem) and "Pretty Boy Swag" (The DeAndre Way).
