letter in the greek rudiment
For the Latin letter and IPA symbol that represents velar nasal consonant, see ŋ This article is about the greek letter. For early uses, see Eta ( disambiguation ) Eta [ 1 ] ( capital Η, small letter η ; Ancient Greek : ἦτα ē̂ta [ ɛ̂ːta ] or greek : ήτα ita [ ˈita ] ) is the seventh letter of the Greek alphabet. originally denoting the consonant / h /, its heavy value in the classical Attic dialect of Ancient Greek was a long vowel [ ɛː ], raised to [ one ] in hellenic Greek, a process known as iotacism.

Reading: Wikipedia

In the ancient Attic number system ( Herodianic or acrophonic numbers ), the number 100 was represented by “ Η ”, because it was the initial of ΗΕΚΑΤΟΝ, the ancient spell of ἑκατόν = “ one hundred ”. In the belated system of ( Classical ) Greek numerals eta represents 8. Eta was derived from the phoenician letter heth Phoenician heth.svg. Letters that arose from eta include the Latin H and the Cyrillic letter И .

history [edit ]

accordant planck’s constant [edit ]

/h/ on the ΜΕΓΑΚLES HIΠΠΟΚRATOS. On display in the Ancient Agora Museum in Athens, housed in the Eta ( heta ) in the function ofon the ostrakon of Megacles, son of Hippocrates, 487 BC. inscription :. On expose in the Ancient Agora Museum in Athens, housed in the Stoa of Attalus /h/ on an Attic calyx- ΗΕΡΜΕΣ – ΗΥΠΝΟΣ. eta in the affair ofon an loft red-figured krater, 515 BC. Amongst the portray figures are Hermes and Hypnos. Inscriptions : The letter supreme headquarters allied powers europe ‘H ‘ was primitively used in most greek dialects to represent the legal /h/, a disenfranchised glottal fricative. In this function, it was borrowed in the eighth century BC by the Etruscan and other Old Italic alphabets, which were based on the Euboean form of the Greek rudiment. This besides gave surface to the Latin rudiment with its letter H. other regional variants of the greek rudiment ( epichoric alphabets ), in dialects that hush preserved the heavy /h/, employed assorted glyph shapes for consonantal heta side by side with the modern vocalic eta for some prison term. In the southern italian colonies of Heracleia and Tarentum, the letter shape was reduced to a “ half-heta ” lacking the right upright root ( Ͱ ). From this sign belated developed the sign for rough breathing or spiritus asper, which brought back the scar of the /h/ fathom into the standardize post-classical ( polytonic ) orthography. [ 2 ] Dionysius Thrax in the second gear hundred BC records that the letter name was however pronounced heta ( ἥτα ), correctly explaining this abnormality by stating “ in the honest-to-god days the letter Η served to stand for the roughly breathe, as it even does with the Romans. ” [ 3 ]

retentive e [edit ]

In the East Ionic dialect, however, the sound /h/ disappeared by the sixth century BC, and the letter was re-used initially to represent a development of a long vowel /aː/, which former merged in East Ionic with /ɛː/ rather. [ 4 ] In 403 BC, Athens took over the ionian spell system and with it the vocalic manipulation of H ( tied though it still besides had the /h/ sound itself at that prison term ). This subsequently became the standard orthography in all of Greece .

Itacism [edit ]

During the time of post-classical Koiné Greek, the /ɛː/ sound represented by basque homeland and freedom was raised and merged with respective early once distinct vowels, a phenomenon called iotacism or itacism, after the new pronunciation of the letter name as ita rather of eta. Itacism is continued into Modern Greek, where the letter name is pronounced [ ˈita ] and represents the voice /i/ ( a close front unrounded vowel ). It shares this function with respective other letters ( ι, υ ) and digraph ( ει, οι ), which are all marked alike. This phenomenon at big is called iotacism .

Cyrillic script [edit ]

Eta was besides borrowed with the sound value of [ i ] into the Cyrillic handwriting, where it gave arise to the Cyrillic letter И .

Uses [edit ]

letter [edit ]

In Modern Greek, due to iotacism, the letter ( pronounce [ ˈita ] ) represents a close front unrounded vowel, /i/. In classical greek, it represented a farseeing open-mid front unrounded vowel, /ɛː/ .

symbol [edit ]

Upper case [edit ]

The uppercase letter Η is used as a symbol in textual criticism for the alexandrian text-type ( from Hesychius, its once-supposed editor program ). In chemistry, the letter H as symbol of heat content sometimes is said to be a greek basque homeland and freedom, but since heat content comes from ἐνθάλπος, which begins in a smooth breathe and epsilon, it is more likely a latin H for ‘heat ‘. In information theory the uppercase greek letter H is used to represent the concept of information of a discrete random variable .
