Grammar
Main article: English grammar

English grammar has minimal inflection compared with most other Indo-European languages. For example, Modern English, unlike Modern German or Dutch and the Romance languages, lacks grammatical gender and adjectival agreement. Case marking has almost disappeared from the language and mainly survives in pronouns. The patterning of strong (e.g. speak/spoke/spoken) versus weak verbs inherited from its Germanic origins has declined in importance in modern English, and the remnants of inflection (such as plural marking) have become more regular.
At the same time, the language has become more analytic, and has developed features such as modal verbs and word order as resources for conveying meaning. Auxiliary verbs mark constructions such as questions, negative polarity, the passive voice and progressive aspect.

Vocabulary

The English vocabulary has changed considerably over the centuries.[36]

Look up Appendix:List of Proto-Indo-European roots inWiktionary, the free dictionary.
Like many languages deriving from Proto-Indo-European (PIE), many of the most common words in English can trace back their origin (through the Germanic branch) to PIE. Such words include the basic pronouns I, from Old English ic, (cf. Latin ego, Greek ego, Sanskrit aham), me (cf. Latin me, Greek eme, Sanskrit mam), numbers (e.g. one, two, three, cf. Latin unus, duo, tres, Greek oinos "ace (on dice)", duo, treis), common family relationships such as mother, father, brother, sister etc (cf. Greek "meter", Latin "mater", Sanskrit "matṛ"; mother), names of many animals (cf. Sankrit mus, Greek mys, Latin mus; mouse), and many common verbs (cf. Greek gignōmi, Latin gnoscere, Hittite kanes; to know).
Germanic words (generally words of Old English or to a lesser extent Norse origin) tend to be shorter than the Latinate words of English, and more common in ordinary speech. This includes nearly all the basic pronouns, prepositions, conjunctions, modal verbs etc. that form the basis of English syntax and grammar. The longer Latinate words are often regarded as more elegant or educated. However, the excessive use of Latinate words is considered at times to be either pretentious or an attempt to obfuscate an issue. George Orwell's essay "Politics and the English Language" is critical of this, as well as other perceived misuse of the language.
An English speaker is in many cases able to choose between Germanic and Latinate synonyms: come or arrive; sight or vision; freedom or liberty. In some cases there is a choice between a Germanic derived word (oversee), a Latin derived word (supervise), and a French word derived from the same Latin word (survey). Such synonyms harbor a variety of different meanings and nuances, enabling the speaker to express fine variations or shades of thought. Familiarity with the etymology of groups of synonyms can give English speakers greater control over their linguistic register. See: List of Germanic and Latinate equivalents in English.
An exception to this and a peculiarity perhaps unique to English is that the nouns for meats are commonly different from, and unrelated to, those for the animals from which they are produced, the animal commonly having a Germanic name and the meat having a French-derived one. Examples include: deer and venison; cow and beef; swine/pig and pork, or sheep and mutton. This is assumed to be a result of the aftermath of the Norman invasion, where a French-speaking elite were the consumers of the meat, produced by Anglo-Saxon lower classes.[citation needed]
Since the majority of words used in informal settings will normally be Germanic, such words are often the preferred choices when a speaker wishes to make a point in an argument in a very direct way. A majority of Latinate words (or at least a majority of content words) will normally be used in more formal speech and writing, such as a courtroom or an encyclopedia article.[citation needed] However, there are other Latinate words that are used normally in everyday speech and do not sound formal; these are mainly words for concepts that no longer have Germanic words, and are generally assimilated better and in many cases do not appear Latinate. For instance, the words mountain, valley, river, aunt, uncle, move, use, push and stay are all Latinate.
English easily accepts technical terms into common usage and often imports new words and phrases. Examples of this phenomenon include: cookie, Internet and URL (technical terms), as well as genre, über, lingua franca and amigo (imported words/phrases from French, German, modern Latin, and Spanish, respectively). In addition, slang often provides new meanings for old words and phrases. In fact, this fluidity is so pronounced that a distinction often needs to be made between formal forms of English and contemporary usage.

Number of words in English
The General Explanations at the beginning of the Oxford English Dictionary states:
“
The Vocabulary of a widely diffused and highly cultivated living language is not a fixed quantity circumscribed by definite limits... there is absolutely no defining line in any direction: the circle of the English language has a well-defined centre but no discernible circumference.
”
The vocabulary of English is undoubtedly vast, but assigning a specific number to its size is more a matter of definition than of calculation. Unlike other languages, such as French, German, Spanish and Italian there is no Academy to define officially accepted words and spellings. Neologisms are coined regularly in medicine, science and technology and other fields, and new slang is constantly developed. Some of these new words enter wide usage; others remain restricted to small circles. Foreign words used in immigrant communities often make their way into wider English usage. Archaic, dialectal, and regional words might or might not be widely considered as "English".
The Oxford English Dictionary, 2nd edition (OED2) includes over 600,000 definitions, following a rather inclusive policy:
“
It embraces not only the standard language of literature and conversation, whether current at the moment, or obsolete, or archaic, but also the main technical vocabulary, and a large measure of dialectal usage and slang (Supplement to the OED, 1933).[37]
”
The editors of Webster's Third New International Dictionary, Unabridged (475,000 main headwords) in their preface, estimate the number to be much higher. It is estimated that about 25,000 words are added to the language each year.[38]
