Corkery, in Synge and Anglo-Irish Literature (1931): literature written in English by Irishmen is now know among us as Anglo-Irish literature, while by Irish literature we mean the literature written in the Irish language and that alone &c. (1947 ed., p.1).

In 1603 Sir John Davies could announce an universal and absolute conquest of all the Irishrie.  Alspach (1959, p.7) quotes Daviess A Discovery of the State of Ireland (1613): the English, both Lords and Free-holders, became degenerate and meer Irish in their language, in their apparell, in their armes and maner of fight They did not only forget the English language and scorne the use thereof, but grew to bee ashamed of their very English Names, though they were noble and of great Antiquity; and tool Irish Surnames and Nickenames.

Toledo divides Englishes in Ireland into Ulster Scots [USc], Anglo-Irish [AI], and Hiberno-English [HE], and later distinguishes between Northern and Southern Hiberno-English [NHE & SHE], refering also to Received Pronounciation [RP], and GAE [General American English].
Hiberno-English: Among the grammatical characteristics of HE regarded as retentions from Irish here noted are the prefacing of questions with an unstressed word (and, well and sure); the avoidance of simple yes/no answers, and the use of reinforcers; Irish rhythms in phatic utterances; claques; a tendency to prefer nominal structures; the use of foregrounding; blended prepositions+pronouns; the use of non-standard be forms to indicate aspectual distinctions; the use of and + NP + Ving for concurrent events; use of a +Ving; the use of untransformed embedded questions, esp. after verbs of mental process; frequent references to God, the devil, and religious sentiments. [36-46]
Gaelic a noun-centred language (Green, The Irish language, 1966, p.31).
George McCartney [sic] reported from Belfast in 1707: .. thank God we are not under any great fears here, for we have not among us above seven papists.
.. it was at bottom the exclusively rural patterm of Gaelic culture which prevented the growrth of an indigenous formal drama. Such drama everywhere has been the product of communal living, has been a town art supported by fixed patronage. Now the Irish never founded a town. The towns and cities of ireland are of Danish, Norman, or English descent. William Smith Clarke, The Early Irish Stage (1955)
Ernest A. Boyd, The Contemporary Drama of Ireland (1918), on Shaw and Wilde: the work of irishmen whose spirit is as remote from their country as the scene in which their plays are laid. (p.4) 
AE Malone (1929): a perfecton of dialogue which is quite distinctively Irish; and they have all the wit whcih is no less a distinguishing mark of the Irishman. They are all satirists, viewing English life with a somewhat disapproving smile Comedies by English writers tend to be humorous and sentimental, while comedies by Irishmen tend to be witty and ironic. (pp.14-15).  FURTHER, on Wilde and Shaw: there is nothing of Ireland in them but the pert dialogue and the ironic wit which is charcateristic of their countrymen at large. (p.15) .
Dion Boucicaults Shaughraun (1874) changed the stereotype of the stage Irishman from feckless rogue to courageous and charming hero.

Una Ellis Fermor attributes the power of Yeatss language to its origin in the speech of Irish peasants, arguing that the unconscious and spontaneous revelation of the living imagination was embodied in the living speech of the people of Ireland in his own day (1964, p.62). 
Yerats knew that words had to be allied to a powerful and passionate syntax (Essays and Introductions, pp.521-22).

Friel: to understand anything about the history or present health of Irish drama, one must first acknowledge the peasant mind. (Times Lit. Suppl., 17 Mar 1972, p.305.)  Friel said, in interview, that he has taken English words and tried to make them distinctive and unique to use (Magill, 1980, p.59) . and note Francis Hardy in Friels Faith Healer, Id recite the names to myself just for the mesmerism, the sedation of the incantation.
The last words in Sam Thomspons Over the Bridge (1970 ed.): A man told me yesterday that when the mob went into action he walked away, and so did hundreds of so-called respectable workmates because they said it was none of their business. None of their business. Rabbie, thats what they said. Then they walked away, and thats what frightens me, they walked away. 
In 1788, Vallancey published an Old Song from Wexford. In it we see a reduced form of Ich am (cham) &c.

(Printed in Alspach, 1959, p.43.) 
Samuel Thompson (1766-1816), anthologised in Montague, ed. (1974, p.170): Fowk tell how though, sae far frae daft,/When wind-faan fruit be scatted saft,/Will row thysel wi cunning craft/An bear awa/Upon thy back, what fares thee aft/A day or twa. 
Antrim James Orr (1770-1816): He weaved himsel an keepet twa three gaun,/What praisd him ay for hale weel-handled yarn;/His thrifty wife an wise wee lasses span,/While warps and queels employd anither barn;/Some stript ilk morn an threshd, the time to earn/To scamper wi the houns frae hill to hill. (Quoted in Akenside & Crawford, 1977, p.17).
Time rins awa an less us a/I say, young men, make haste,/For if you don, shell say she wont,/Whut joys yell nivir taste. (Lynn, 1991, p.16).

Gavan Duffy Ballad Poetry of Ireland (1845) gives Lillibullero
An early translator of Keating was Dermod OConnor, whose first folio ed. appeared in 1723. The Institutes of Bryen Boroimhe/so wholesome for the support of Virtue,/Were kept with so much Reverence and Regard,/That a young lady of consummate Beauty,/Adornd with Jewels and a Ring of gold;/Travelled alone on Foot from North to South/and no attempt was made upon her Honour,/Or to divest her of the Cloaths she wore (Alspach, 1959, p.93). 
Charlotte Brooke: I care not for thee, senseless clerk!/Nor all they psalming throng/Whose stupid souls, unwisely dark,/Reject the light of song (Reliques, 1789, p.37) . Also Now old,the streams of life congeald/Bereft of all my joys!/No sword this withered hand can wield,/No spear my arm employs.
Theophilus OFlanagan (1762-1814) uses alliteration in translating Deirdres lament on leaving Scotland for Ulster:Sweet is the cuckoos note on bending bough/On the cliff over the vale of the two Roes. (Transactions of the Gaelic Society, 1806, p.51.) 
Fergusons Congal uses what Lucy calls the word cataracts of medieval Irish:the deep-clear-watered, foamy crested, terribly-resounding,/Lofty leaping, prone descending, ocean-calf-abounding,/Fishy fruitful, salmon-teeming, many coloured, sunny beaming,/Heady-eddied, horrid thundring, ocean-progeny-engendring,/Billow-raging, battle-waging, merman-haunted, poet-vaunted,/Royal, patrimonial, old torrent of Eas-Roe. (Congal, 1872).
RUIN: In Moores Believe me if all those endearing young charms. Believe me if all those endearing young charms/Which I gaze on so fondly today,/Were to change by to-morrow, and fleet in my arms,/Like fairy-gofts fading away,/Thou would stillbe adord, as this moment thou art,/Let thy loveliness fade as it will/An around the dear ruin each wish of my heart/Would entwine itself verdantly still. (ed. Godley, 1915, p.189).
RUIN: Thomas Davis, Tones Grave: My heart overflowed, and I clasped his old hand,/And I blessed him, and blessed every one of his band;/Sweet, sweet tis to find that such faith can remain/To the cause and the man so long vanquished and slain./In Bodenstown churchyard there is a green grave,And freely around it let winter winds rave -/Far better they suit himthe ruin and the gloom/till Ireland, a nation, can build him a tomb. (The 98 Song Book, n.d., p.12).
Other modern ballads are The Dying Rebel [dear Cork city], and Boolavogue [brave Father Murphy]. God grant you glory, Father Murphy,/and open heaven to all your men;/The cause that called you may call tomorrow/In another fight for the Green again.

WG Lyttle, Betsy Gray: or Hearts of Down: A Tale of Ninety-Eight (1888); a prolific writer, keenly interested in the representation of dialect. Toledo quotes a passage illustrating the use of Ulster Scots and Standard English for two roles, that of Mat, the lower-class character, and George Gray, the educated character, though both of Scots origin. At the close of the passage, however, Gray uses HE foregrounding, Its joking you are, Mat, he exclaimed.

Yeats once criticised the people in Colums plays, saying that they were not the true folk. They are the peasant as he is being transformed by modern life. [It is the speech of the people] who think in English, and shows the influence of the newspaper and the national schools. (Explorations, Macmillan 1962, p.183) 
According to de Blacam, English Morality palys were actedand transcirbedin dublin, early in [the fifteenth] century.
