Spelling Timeline

Foreword
This is Hurlebatte's, attempt at following the evolution of English spelling. Do not take it as authoritative or fully accurate.

600-1066
The English alphabet consists of the following: Aa Bb Cc Dd Ee Ff Gg Hh Ii Kk Ll Mm Nn Oo Pp Rr Ss Tt Uu Xx Yy Þþ Ðð Ƿƿ Ææ.


 * Digraphs include: ⟨cg⟩ and ⟨gc⟩ for /dʒ/; ⟨sc⟩ for /ʃ/; ⟨ea⟩ for /æɑ/; ⟨uu⟩ for /w/; ⟨th⟩ for /θ/; ⟨hƿ⟩ for /ʍ/; ⟨ch⟩ for /x/.
 * ⟨ƿ⟩ is not universally used; some writers use ⟨u⟩ or ⟨uu⟩ instead. Sometimes ⟨uu⟩ is written as a ligature, a practice which would eventually result in the full-fledged letter ⟨w⟩.
 * ⟨k⟩ sometimes shows up to fight ambiguity between /tʃ/ and /k/. Bodleian Library MS. Auct. D. 2. 19 from the early 800s is an early example.
 * ⟨þ⟩ and ⟨ð⟩ are used interchangeably, though there seems to have been a slight preference for using ⟨þ⟩ initially and ⟨ð⟩ elsewhere. On folio 8v of Cotton Titus D 18, both ⟨þ⟩ and ⟨ð⟩ are named thorn, implying that some Englishmen may have seen them as two versions of the same letter.
 * ⟨z⟩ and ⟨q⟩ are very rare. ⟨z⟩ can sometimes be found in foreign names like Zenodotus, as in Ashmole 328.
 * ⟨e⟩ and ⟨i⟩ are occasionally inserted after ⟨c⟩ and ⟨g⟩ when writers want to make it clear their values are /tʃ/ and /j/ and not /k/ and /g/. For example, giul can be found as a spelling for /jul/ (Yule).

1066-1199
The Norman Invasion occurs, French begins to influence English orthography.


 * In the Peterborough Chronicle a switch in handwriting from Insular to Carolingian happens on folio 88v.


 * ⟨gg⟩ becomes more popular than ⟨cg⟩.


 * The Ormulum uses: ⟨ch⟩ for /tʃ/, ⟨sk⟩ for /sk/; ⟨sh⟩ for /ʃ/; ⟨ƿh⟩ for /ʍ/; Carolingian ⟨g⟩ for /g/; ⟨ȝh⟩ for [ɣ]; ⟨ȝȝ⟩ for /dʒ/.


 * The Carolingian style of writing ⟨g⟩ is borrowed from France. The old Insular ⟨g⟩ becomes the new letter ⟨ȝ⟩, called yough. ⟨ȝ⟩ no longer stands for /g/, as this job now belongs to the Carolingian ⟨g⟩.


 * By now /y/ has merged into /i/. This leads to ⟨y⟩ being used interchangeably with ⟨i⟩. This may be the basis for ⟨y⟩ later taking on /j/. It seems that in a few cases surviving instances of /y/ get respelled as ⟨u⟩ in the French manner, resulting in variant spellings like burthen and brugge as opposed to birthen and brigge.


 * ⟨u⟩ begins showing up with the value of /v/ shortly after 1066, as on folio 116v of Cotton Tiberius A 13.


 * ⟨hr⟩ struggles to survive this period, usually becoming ⟨r⟩.


 * ⟨hl⟩ often becomes ⟨l⟩.

1200s
By this century the Normans have been replaced on the throne by the Angevins. French influence continues, though not necessarily Norman French.


 * /ʃ/ is spelled ⟨sc⟩, ⟨sch⟩, ⟨sh⟩, ⟨ss⟩, ⟨s⟩.


 * ⟨ou⟩ is borrowed from French and becomes a very popular spelling for /uː/, which beforehand was written ⟨u⟩, ⟨ue⟩, and ⟨uCe⟩.


 * ⟨ue⟩ and ⟨uCe⟩ are repurposed to stand for French /y/. This French /y/ seems to have been substituted by Englishmen for something along the lines of [ɛu], a native English diphthong. This French /y/ and the native [ɛu] would both eventually be pronounced as /ju/. Because the borrowed French /y/ was realised as something like [ɛu], native English words with [ɛu] would sometimes be respelled with ⟨ue⟩ or ⟨uCe⟩, which is why clue is not spelled clew today.


 * ⟨ð⟩ falls out of wide use by the end of the century.


 * The distinction between [x] and [ɣ] either collapses or people stop caring. [x] had usually been written ⟨h⟩ (more rarely ⟨ch⟩), and [ɣ] had usually been written ⟨ȝ⟩, but ⟨ȝ⟩ ends up being the normal way of writing both. Eventually ⟨ȝh⟩ becomes popular, perhaps under influence of French or French-linked digraphs like ⟨ch⟩ and ⟨sh⟩.


 * ⟨æ⟩ seems to drop out of use by the end of this century. Its short value merged with ⟨a⟩, while its long value began to be written ⟨ea⟩. Contrary to a claim made in The History of English Spelling, by Upward & Davidson, ⟨ea⟩ was probably not "borrowed by French scribes from Old English", as it survived into the 1100s (Laud Manuscript) and 1200s in words like head.
 * ⟨hw⟩ has essentially been fully replaced with ⟨wh⟩ by the end of this century.


 * ⟨y⟩ for /j/ can be found in *St.Marg.(2) (Trin-C B.14.39).


 * ⟨hl⟩ fully dies off?


 * Vowel breaking leads to spellings like ⟨ou⟩ and ⟨ei⟩ in words like dough and height.

1300s
The English alphabet generally consists of the following: Aa Bb Cc Dd Ee Ff Gg Hh Ii Kk Ll Mm Nn Oo Pp Qq Rr Ss Tt Uu Xx Yy Þþ. Jj, Vv, and Ww are becoming full-fledged letters. I do not know if Ȝȝ was considered independent of Gg in this time period, though it was certainly used as though it were its own letter.


 * ⟨uCe⟩ can still be found standing for /uː/, though ⟨ou⟩ is more popular.


 * ⟨ck⟩ rises as a popular spelling.


 * ⟨gh⟩ appears, apparently modelled on ⟨ȝh⟩, and taking the job of /x/.


 * ⟨y⟩ begins to be a popular alternative to ⟨ȝ⟩ for making /j/.


 * By the end of this century ⟨ȝ⟩ has lost much ground to ⟨y⟩ and ⟨gh⟩.


 * Loanwords from French with initial /dʒ/ can be found written with ⟨i⟩, ⟨ih⟩, and ⟨g⟩. Eventually ⟨j⟩ would be used for /dʒ/ instead of ⟨i⟩ and ⟨ih⟩.


 * ⟨dg⟩ shows up in Trev.Higd.(StJ-C H.1)5.123.


 * ⟨ð⟩ is rare and seems to die in this century.


 * ⟨wl⟩ dies off and becomes ⟨l⟩.


 * After a long period of disuse, ⟨th⟩ begins popping up around the end of this century.

1400s

 * Continuing a trend that began in the second half of the 1300s, ⟨th⟩ continues to rise in popularity, even in manuscripts like Harley MS 682 where ⟨þ⟩ and ⟨y⟩ still had distinct shapes. Printing presses came later, so they did not cause this.


 * Harley MS 682 uses ⟨gh⟩ dozens of times, but ⟨ȝ⟩ only twice. The manuscript contains no ⟨z⟩, implying that the writer did not avoid ⟨ȝ⟩ on account of it looking too much like ⟨z⟩.


 * ⟨ȝh⟩ is used in a few manuscripts for /j/, but the common use of ⟨ȝh⟩ is for /x/.


 * ⟨x⟩ is used by some writers for /ʃ/.


 * ⟨h⟩ can still be found standing for /x/, though rarely.


 * ⟨dg⟩ becomes more popular, though ⟨gg⟩ still seems dominant.

1500s


 * By the end of this century, spellings like bed have mostly replaced spellings like bedde?


 * ⟨dg⟩ becomes more common than ⟨gg⟩?


 * ⟨oo⟩ and ⟨ee⟩ gain some popularity.


 * ⟨oa⟩ gains some popularity, leading to spellings like boat and goat where English previously had bote and gote.
