Although French is mainly from Latin (which accounts for about 60% of English vocabulary either directly or via a Romance language), it also includes words from Gaulish and Germanic languages (especially Old Frankish). Since English is of Germanic origin, words that have entered English from the Germanic elements in French might not strike the eye as distinctively from French. Conversely, as Latin gave many derivatives to both the English and the French languages, ascertaining that a given Latinate derivative did not come to the English language via French can be difficult in a few cases.
Most of the French vocabulary now appearing in English was imported over the centuries following the Norman Conquest of 1066, when England came under the administration of Norman-speaking peoples. William the Conqueror invaded the island of Britain, distributing lands and property to the Normans. As a result, French became the language of culture and the administration. The majority of the population of England continued to use their Anglo-Saxon language, but it was influenced by the language of the ruling elite, resulting in doublets. Consider for example the words for the meats eaten by the Anglo-Norman nobility and the corresponding animals raised by the Anglo-Saxon peasants: beef / ox, mutton / sheep, veal / calf, pork / pig, or pairs of words pertaining to different registers of language: commence / start, continue / go on, disengage / withdraw, encounter / meet, vend / sell, purchase / buy, commerce / trade. Words of French origin often refer to more abstract or elaborate notions than their Anglo-Saxon equivalents (e.g. liberty / freedom, justice / fairness), and are therefore of less frequent use in everyday language. This may not, however, be the case for all English words of French origin. Consider, for example: able, car, chair, city, country, fine, fruit, journey, juice, just, part, people, real, stay, table, travel, use, very, and wait.
After the rise of Henry Plantagenet to the throne of England, other forms of dialectal French may have gained in influence to the detriment of Norman French (notably the variants of Anjou where the House of Plantagenet came from, and possibly Poitevin, the tongue of Eleanor of Aquitaine). With the English claim to the throne of France, the influence of the language in use at the royal court of France in Paris increased. The cultural influence of France remained strong in the following centuries and from the Renaissance onward borrowings were mainly made from Parisian French, which became the de facto standard language of France.
Norman rule of England had a lasting impact on British society. Words from Anglo-Norman or Old French include terms related to Chivalry (homage, liege, peasant, government, seigniorage, suzerain, vassal, villain) and other institutions (bailiff, chancellor, council, government, mayor, minister, parliament), the organisation of religion (abbey, clergy, cloister, diocese, friar, mass, parish, prayer, preach, priest, sacristy, vestment, vestry, vicar), the nobility (baron, count, dame, duke, marquis, prince, sir), and the art of war (armour, baldric, dungeon, hauberk, mail, portcullis, rampart, surcoat). Many of these words related to the feudal system or medieval warfare have a Germanic origin (mainly through Old Frankish) (see also French words of Germanic origin).
Sometimes used in heraldry, some mythological beasts (cockatrice, dragon, griffin, hippogriff, phoenix) or exotic animals (lion, leopard, antelope, gazelle, giraffe, camel, zebu, elephant, baboon, macaque, mouflon, dolphin, ocelot, ostrich, chameleon) draw their name from French. It is also the case of some animals native of Europe (via Anglo-Norman: eagle, buzzard, falcon, squirrel, coney, rabbit, leveret, lizard, marten, ferret, salmon, viper).
