^Although the letter Λ is almost universally known today as lambda (λάμβδα), the most common name for it during the Greek Classical Period (510–323 BC) appears to have been labda (λάβδα), without the μ.
^The letter sigmaStampa:Angbr has two different lowercase forms in its standard variant, Stampa:Angbr and Stampa:Angbr, with Stampa:Angbr being used in word-final position and Stampa:Angbr elsewhere.[7][12][13] In some 19th-century typesetting, Stampa:Angbr was also used word-medially at the end of a compound morpheme, e.g. "δυςκατανοήτων", marking the morpheme boundary between "δυς-κατανοήτων" ("difficult to understand"); modern standard practice is to spell "δυσκατανοήτων" with a non-final sigma.[13] The letter sigma also has an alternative variant, the lunate sigma (uppercase Ϲ, lowercase ϲ), which is used in all positions.[7][12][14] This form of the letter developed during the Hellenistic period (323–31 BC) as a simplification of the older Σ σ/ς variant.[14] Thus, the word stasis can either be written στάσις or ϲτάϲιϲ.[15] In modern, edited Greek texts, the lunate sigma typically appears primarily in older typesetting.[12]
