Noun

A noun (from Latin nōmen, literally meaning "name") is a word that functions as the name of some specific thing or set of things, such as living creatures, objects, places, actions, qualities, states of existence, or ideas. Linguistically, a noun is a member of a large, open part of speech whose members can occur as the main word in the subject of a clause, the object of a verb, or the object of a preposition.

Lexical categories (parts of speech) are defined in terms of the ways in which their members combine with other kinds of expressions. In English, nouns are those words which can occur with articles and attributive adjectives and can function as the head of a noun phrase.

Complement

In grammar, a complement is a word, phrase or clause that is necessary to complete the meaning of a given expression. Complements are often also arguments (expressions that help complete the meaning of a predicate.

There are indicative as well as non-indicative complements in languages. Non-indicative complements follow the appropriate complementizers. Indicative complements do not follow complementizers but instead are included with special markers and clauses.

In many non-theoretical grammars, the terms subject complement and object complement are employed to denote the predicative expressions that serve to assign a property to a subject or an object:

• Ryan is upset. – Predicative adjective as subject complement
• Rachelle is the boss. – Predicative nominal as subject complement
• That made Michael lazy. – Predicative adjective as object complement
• We call Rachelle the boss. – Predicative nominal as object complement

The Cambridge Grammar of the English Language assigns the term "predicative complement" to both uses and shifts the terminological distinction to the verb:

• Ed seemed quite competent: — complex-intransitive verb + predicative complement
• She considered Ed quite competent : — complex-transitive verb + predicative complement

In many modern grammars, the object argument of a verbal predicate is called a complement. In fact, this use of the term is the one that currently dominates in linguistics. A main aspect of this understanding of complements is that the subject is usually not a complement of the predicate:

• He *wiped the counter*. – the counter is the object complement of the verb wiped.
• She *scoured the tub*. – the tub is the object complement of the verb scoured.

Questions

Like many other Western European languages, English historically allowed questions to be formed by inverting the positions of verb and subject. Modern English permits this only in the case of a small class of verbs ("special verbs"), consisting of auxiliaries as well as forms of the copula be. To form a question from a sentence which does not have such an auxiliary or copula present, the auxiliary verb do (does, did) needs to be inserted, along with inversion of the word order, to form a question. For example:

• She can dance. → Can she dance? (inversion of subject she and auxiliary can)
• I am sitting here. → Am I sitting here? (inversion of subject I and copula am)
• The milk goes in the fridge. → Does the milk go in the fridge? (no special verb present; do-support required)

The above concerns yes-no questions, but inversion also takes place in the same way after other questions, formed with interrogative words such as where, what, how, etc. An exception applies when the interrogative word is the subject or part of the subject, in which case there is no inversion. For example:

• I go. → Where do I go? (wh-question formed using inversion, with do-support required in this case)
• He goes. → Who goes? (no inversion, because the question word who is the subject)

Note that inversion does not apply in indirect questions: I wonder where he is (not ... where is he). Indirect yes-no questions can be expressed using if or whether as the interrogative word: Ask them whether/if they saw him*.

Negative questions are formed similarly; however if the verb undergoing inversion has a contraction with not, then it is possible to invert the subject with this contraction as a whole. For example:

• John is going. (affirmative)
• John is not going. / John isn't going. (negative, with and without contraction)
• Isn't John going? / Is John not going? (negative question, with and without contraction respectively)

Tag questions are formed with a special verb and pronoun subject: isn't it?; were there?; am I not?

A2 / Elementary / Pre-intermediate

A CEFR A2 level English language user is considered to be at an elementary level. At this level, an individual is expected to have a basic understanding of the English language and be able to use simple phrases and sentences to communicate in everyday situations. They should be able to understand and use basic grammar and vocabulary, and be able to understand short, simple texts.

At A2 level, They can understand sentences and frequently used expressions related to areas of most immediate relevance (e.g. very basic personal and family information, shopping, local geography, employment). They can communicate in simple and routine tasks requiring a simple and direct exchange of information on familiar and routine matters. They can describe in simple terms aspects of their background, immediate environment and matters in areas of immediate need. They can also interact with a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible without strain for either party.
