Szugma is a silent and invisible letter that has eluded detection for millenia. We only know of its existence due to interference among other letters, suggesting the presence of an unobserved letter. Grammologists and linguists liken this scenario to the Higg's boson predicted by String Theory in physics. From this proposition, one might conclude that letters are natural phenomena inherent to the universe and independent of human language. However, this theory is controversial: letters may be inherent and waiting to be discovered like particles in physics, or they may have been invented by ancient peoples and forgotten, only detected through careful analysis of interference patterns. Suffice to say, no one has seen or heard a szugma directly, and the discovery of this elusive letter would be one of the great accomplishments of mankind.
