Preposition

Prepositions form a closed word class, although there are also certain phrases that serve as prepositions, such as in front of.

A single preposition may have a variety of meanings, often including temporal, spatial and abstract. Many words that are prepositions can also serve as adverbs. Examples of common English prepositions (including phrasal instances) are of, in, on, over, under, to, from, with, in front of, behind, opposite, by, before, after, during, through, in spite of or despite, between, among, etc.

A preposition is usually used with a noun phrase as its complement.

A preposition together with its complement is called a prepositional phrase.

Examples are in England, under the table, after six pleasant weeks, between the land and the sea.

A prepositional phrase can be used as a complement or post-modifier of a noun in a noun phrase, as in the man in the car, the start of the fight; as a complement of a verb or adjective, as in deal with the problem, proud of oneself; or generally as an adverb phrase.

English allows the use of "stranded" prepositions. This can occur in interrogative and relative clauses, where the interrogative or relative pronoun that is the preposition's complement is moved to the start (fronted), leaving the preposition in place. This kind of structure is avoided in some kinds of formal English.

For example:

• What are you talking about? (Possible alternative version: About what are you talking?)
• The song that you were listening to ... (more formal: The song to which you were listening ...)

Notice that in the second example the relative pronoun that could be omitted.

Stranded prepositions can also arise in passive voice constructions and other uses of passive past participial phrases, where the complement in a prepositional phrase can become zero in the same way that a verb's direct object would: it was looked at; I will be operated on; get your teeth seen to.

The same can happen in certain uses of infinitive phrases: he is nice to talk to; this is the page to make copies of.

Verb

Verbs constitute one of the main word classes in the English language. Like other types of words in the language, English verbs are not heavily inflected. Most combinations of tense, aspect, mood and voice are expressed periphrastically, using constructions with auxiliary verbs.

Generally, the only inflected forms of an English verb are a third person singular present tense form in -s, a past tense, a past participle (which may be the same as the past tense), and a form ending in -ing that serves as a present participle and gerund. Most verbs inflect in a simple regular fashion, although there are about 200 irregular verbs; the irregularity in nearly all cases concerns the past tense and past participle forms. The copula verb be has a larger number of different inflected forms, and is highly irregular.

A typical English verb may have five different inflected forms:

• The base form or plain form (go, write, climb), which has several uses—as an infinitive, imperative, present subjunctive, and present indicative except in the third-person singular
• The -s form (goes, writes, climbs), used as the present indicative in the third-person singular
• the past tense or preterite (went, wrote, climbed)
• The past participle (gone, written, climbed) – this is identical to the past tense in the case of regular verbs and some irregular ones (here the first two verbs are irregular and the third regular)
• The -ing form (going, writing, climbing), used as a present participle, gerund, and (de)verbal nounThe verb be has a larger number of different forms (am, is, are, was, were, etc.), while the modal verbs have a more limited number of forms.

Some forms of be and of certain other auxiliary verbs also have contracted forms ( 's, 're, 've, etc.).

In English, verbs frequently appear in combinations containing one or more auxiliary verbs and a nonfinite form (infinitive or participle) of a main (lexical) verb.

Examples

The first verb in such a combination is the finite verb, the remainder are nonfinite (although constructions in which even the leading verb is nonfinite are also possible – see below). Such combinations are sometimes called compound verbs; more technically they may be called verb catenae, since they are not generally strict grammatical constituents of the clause.

• The dog was barking very loudly.
• My hat has been cleaned.
• Jane does not really like us.

As the last example shows, the words making up these combinations do not always remain consecutive.

Tenses, Aspects and Moods

The means English uses for expressing the three categories of tense (time reference), aspect and mood are somewhat conflated. English has only limited means for expressing these categories through verb conjugation, and tends mostly to express them periphrastically, using the verb combinations mentioned in the previous section. The tenses, aspects and moods that may be identified in English are described below (although the terminology used differs significantly between authors). Note that in common usage, particular tense–aspect–mood combinations such as "present progressive" and "conditional perfect" are often referred to simply as "tenses".

Phrasal Verbs

In English, a phrasal verb is a phrase such as turn down or ran into which combines two or three words from different grammatical categories: a verb and a particle and/or a preposition together form a single semantic unit. This semantic unit cannot be understood based upon the meanings of the individual parts, but must be taken as a whole. In other words, the meaning is non-compositional and thus unpredictable. Phrasal verbs that include a preposition are known as prepositional verbs and phrasal verbs that include a particle are also known as particle verbs. Additional alternative terms for phrasal verb are compound verb, verb-adverb combination, verb-particle construction, two-part word/verb, and three-part word/verb (depending on the number of particles), and multi-word verb.

Examples

There are at least three main types of phrasal verb constructions depending on whether the verb combines with a preposition, a particle, or both. The phrasal verb constructions in the following examples are in bold:

Verb + preposition (prepositional phrasal verbs)

When the element is a preposition, it is the head) of a full prepositional phrase and the phrasal verb is thus a prepositional phrasal verb. These phrasal verbs can also be thought of as transitive and non-separable; the complement follows the phrasal verb.

• Who is looking after the kids? – after is a preposition that introduces the prepositional phrase after the kids.
• They picked on nobody. – on is a preposition that introduces the prepositional phrase on nobody.
• I ran into an old friend. – into is a preposition that introduces the prepositional phrase into an old friend.
• She takes after her mother. – after is a preposition that introduces the prepositional phrase after her mother.
• Sam passes for a linguist. – for is a preposition that introduces the prepositional phrase for a linguist.
• You should stand by your friend. – by is a preposition that introduces the prepositional phrase by your friend.

Verb + particle (particle phrasal verbs)

When the element is a particle, it can not (or no longer) be construed as a preposition, but rather is a particle because it does not take a complement. These verbs can be transitive or intransitive. If they are transitive, they are separable.

• They brought that up twice. – up is a particle, not a preposition.
• You should think it over. – over is a particle, not a preposition.
• Why does he always dress down? – down is a particle, not a preposition.
• You should not give in so quickly. – in is a particle, not a preposition.
• Where do they want to hang out? – out is a particle, not a preposition.
• She handed it in. – in is a particle, not a preposition. *

Verb + particle + preposition (particle-prepositional phrasal verbs)

Finally, many phrasal verbs are combined with both a preposition and a particle.

• Who can put up with that? – up is a particle and with is a preposition.
• She is looking forward to a rest. – forward is a particle and to is a preposition.
• The other tanks were bearing down on my panther. – down is a particle and on is a preposition.
• They were really teeing off on me. – off is a particle and on is a preposition.
• We loaded up on Mountain Dew and Doritos. – up is a particle and on is a preposition
• Susan has been sitting in for me. – in is a particle and for is a preposition.The aspect of these types of verbs that unifies them under the single banner phrasal verb is the fact that their meaning cannot be understood based upon the meaning of their parts taken in isolation: the meaning of pick up is distinct from pick; the meaning of hang out is not obviously related to hang.

A1 / Elementary / Beginners

A CEFR A1 level English language user is considered a beginner. At this level, an individual is expected to have a basic understanding of the English language, including basic vocabulary and grammar. They should be able to understand and use simple phrases and sentences in order to meet basic needs and engage in simple, everyday conversations. They should also be able to understand simple instructions and signs in English.

At A1 level, they are able to understand and use familiar everyday expressions and very basic phrases aimed at the satisfaction of needs of a concrete type. They can introduce him/herself and others and can ask and answer questions about personal details such as where he/she lives, people he/she knows and things he/she has. They can interact in a simple way provided the other person talks slowly and clearly and is prepared to help.
