- In 1066, the Anglo-Saxons suffer more losses against the Norwegians at Stamford Bridge, but still win. Accordingly, William has a numerical advantage at Hastings, with fewer casualties and more surviving Normans in the initial conquest, at least an extra thousand. (While this would be a small difference at first, the population would multiply over time).
- In the 1070s and 1080s, chaotic wars between Philip I of France, the Count of Flanders, and the Duke of Brittany lead to the displacement and exile of many nobles, increasing French elite settlement in England.
- Throughout the 1100s, 1200s, and 1300s, the English manage to conquer all of France, with the Kingdoms of England and France being held by the same monarch for centuries. During this time, French burghers, nobles, priests, and traders settle in England in significant numbers. Even free farmers* from France settle in England (which would have had cheaper land than France). From time to time, French soldiers are also garrisoned in England when the King has to put down rebellions in the north. Meanwhile, English and Anglo-Norman lords who are placed in France, thereafter assimilate and become "more French than the French".
- In the 1400s and early 1500s, the Kingdoms of France and England are once again split in a decades-long war. In the process, a great number of Frenchified English lords, with armies and courts of equally French loyalists, resettle in England once it is clear that the King of England will never reconquer France.
- In the early 1500s, though the English are already much more French influenced, they attempt to forge an independent identity by separating from the Roman Catholic Church. The increasing power of Parliament also leads to increased influence of "English" speaking non-nobles, preventing English from being assimilated completely by French, but by this point the language is already more Romance.
- In the late 1500s, something similar to the Spanish Armada occurs, except in this world the invasion is successful. The King of Spain and England brutally crushes the heretics, placing Spanish lords and settling in Spanish and French speaking Catholics from the continent to keep his rule over the island.
- In the 1600s, England manages to break off from Spain during a crisis in the Holy Roman Empire (similar to the Thirty Years' War). However, the Catholicization of England is complete, like OTL Bohemia. By now, many noble houses are Spanish, and the Spanish language has almost as much prestige as French.
- In the 1700s and 1800s, "Scientific Latin" (and Greek) becomes particularly popular for written works. Sophisticated new vocabulary is introduced especially in newly-appearing technical fields.
- In the 1800s, after a revolution and counterrevolution, the English welcome a liberal Italian king, who brings in Italian advisers, bureaucrats, and artists. Towards the end of the century, the use of French and Spanish is abandoned, and "Anglais" is favored.
- In the 1900s, increasing literacy advances the popularity of Neo-Latin derived literary terms into common speech.
- In the 2000s, the "Anglais" wonder what their language would have been like without the Norman Conquest.
* There actually were some free farmers who owned their own land in the Middle Ages, such as the parents of Joan of Arc.
