Englische Präpositionen und Phrasal Verbs

Prepositions of Time: At, On, and In

English prepositions of time follow specific rules based on the precision and duration of the period being discussed. We use the preposition $at$ primarily for specific times of the day, such as $at$ $5$ o'clock, $at$ $11.45$, $at$ midnight, $at$ lunchtime, and $at$ sunset. We use $on$ for specific days and dates, including single days like $on$ Friday or repeating days like $on$ Fridays, as well as specific calendar dates like $on$ $16$ May $2012$, and holidays like $on$ New Year's Day or personal events like $on$ my birthday. The preposition $in$ is reserved for longer periods, which encompasses months (e.g., $in$ June), years (e.g., $in$ $2012$), decades (e.g., $in$ the $1990s$), centuries (e.g., $in$ the $20th$ century), historical eras (e.g., $in$ the past), and seasons (e.g., $in$ winter).

There are several set expressions involving these prepositions. We say $at$ the moment, $at$ the minute, $at$ present, or $at$ this time to mean now. We also say $at$ the same time. In British English, the standard is $at$ the weekend or $at$ weekends, while American English often uses $on$ the weekend or $on$ weekends. For holidays, we use $at$ for the general period, such as $at$ Christmas, but $on$ for the specific day, such as $on$ Christmas Day. For the word night, we use $at$ night to refer to nights in general, but $in$ the night to refer to a specific occurrence, such as being woken up by a noise $in$ the night. For different parts of the day, we say $in$ the morning, $in$ the afternoon, and $in$ the evening; however, if we specify the day with the part of the day, the preposition changes to $on$, as in $on$ Friday morning or $on$ Sunday afternoon.

Critically, we do not use the prepositions $at$, $on$, or $in$ before the words last, next, this, or every. For example, we say I will see you next Friday rather than on next Friday. Additionally, the preposition $on$ is often omitted before days in informal speech, allowing for phrases like I will see you Friday instead of on Friday. The preposition $in$ is also used to indicate a future point in time, such as $in$ a few minutes meaning a few minutes from now, or to describe the duration it takes to complete a task, such as learning to drive $in$ four weeks.

Nuances of Punctuality and Timing: On Time, In Time, At the End, and In the End

The phrase $on$ time means to be punctual or according to a planned schedule. If a train leaves $on$ time, it leaves exactly at its scheduled hour, such as $at$ $11.45$. Conversely, $in$ time means soon enough for a specific purpose. For instance, being home $in$ time for dinner means arriving before it starts. The phrase just $in$ time is used to denote being almost too late, such as stopping a car just $in$ time to avoid hitting a child. The opposite of $in$ time is too late.

There is a distinct difference between $at$ the end and $in$ the end. We use $at$ the end of something to describe a specific point in time when an event concludes, such as $at$ the end of the month, $at$ the end of the film, or $at$ the end of the concert. The opposite of this is $at$ the beginning. We never say in the end of. The phrase $in$ the end is used as an adverbial meaning finally, to describe the ultimate result of a complicated or lengthy situation. For example, if someone has car trouble and eventually decides to sell the vehicle, they sold it $in$ the end. The opposite of $in$ the end is at first.

Prepositions of Position: In, At, and On

The preposition $in$ relates to three-dimensional spaces or areas with boundaries. This includes being $in$ a room, $in$ a building, $in$ a box, $in$ a garden, $in$ a town, or $in$ a city centre. It also applies to bodies of water like being $in$ the sea, $in$ a river, or $in$ a pool. We use $at$ for a specific point or location, such as $at$ the bus stop, $at$ the door, $at$ the traffic lights, or $at$ the roundabout. It is also used for specific desks or stations, such as $at$ reception. When comparing the two, being $in$ a shop means being inside the physical building, while being $at$ the shop might mean it is a point on a journey or a meeting place outside.

The preposition $on$ is used for surfaces and specific linear or horizontal positions. This includes being $on$ the wall, $on$ the ceiling, $on$ a page, $on$ an island, or $on$ the floor. We also use $on$ for the left or right sides and for specific floors of a building, such as being $on$ the second floor. For certain items, we distinguish by intent: some water is $in$ the bottle, but a label is $on$ the bottle. Similarly, someone may be $at$ the door (standing near it), but a notice is $on$ the door (attached to the surface).

Standard Expressions for Locations and Transport

Specific set phrases exist for common locations. We say someone is $in$ bed, $in$ hospital, or $in$ prison. However, we use $at$ for institutional or social contexts like being $at$ home, $at$ work, $at$ school, $at$ university, or $at$ college. We also use $at$ for events and social gatherings, such as being $at$ a party, $at$ a concert, $at$ a conference, or $at$ a wedding. When referring to buildings, we often use $at$ to treat them as a point of reference or a place where an event occurs (e.g., we had dinner $at$ the hotel), but $in$ when focusing on the interior space (e.g., all the rooms $in$ the hotel have air conditioning).

Regarding transport, we generally use $on$ for public or large-scale transportation, such as being $on$ a bus, $on$ a train, $on$ a plane, or $on$ a ship. We also use $on$ for smaller two-wheeled transport or animals, such as being $on$ a bike, $on$ a motorbike, or $on$ a horse. In contrast, we use $in$ for private vehicles like being $in$ a car or $in$ a taxi. For towns and cities, we normally use $in$ (e.g., The Louvre is $in$ Paris), but we use $at$ when considering the town as a stopping point on a journey, such as a train stopping $at$ Oxford.

Prepositions of Movement and Entry: To, Into, and Arrive

We use the preposition $to$ for movement toward a destination or event, such as traveling $to$ China, going $to$ work, or being taken $to$ hospital. This is distinct from $in$ and $at$, which denote position. For example, one goes $to$ France but lives $in$ France. The phrase been $to$ is used to describe completed visits. When discussing arrival, we use get $to$ for most places, but the verb arrive takes either $in$ or $at$. We arrive $in$ a town or country (e.g., arrive $in$ Madrid) and arrive $at$ specific buildings or events (e.g., arrive $at$ the airport).

The word home is unique because it generally does not take a preposition when indicating movement. We say go home or arrive home rather than to home. However, for position, we can say $at$ home. The preposition $into$ describes the action of entering a space, such as walking $into$ a room or a bird flying $into$ a kitchen. We often use $in$ as a shorter alternative for $into$ with verbs like put, get, or go. The opposite of $into$ is out of. For boarding vehicles, we use the specific phrasal verbs get $on$ and get off for buses, trains, and planes, but get $into$ and get out of for cars and taxis.

Specialized and Abstract Uses of Prepositions

Prepositions also serve abstract grammatical functions. We use $in$ for weather conditions (e.g., sitting $in$ the shade, walking $in$ the rain), languages (e.g., saying thank you $in$ Russian), and emotional states (e.g., being $in$ love, being $in$ a bad mood). We use $on$ for communication media such as being $on$ TV, listening $on$ the radio, or talking $on$ the phone, as well as for functional states like being $on$ fire, $on$ purpose, $on$ holiday, $on$ business, or $on$ a diet. Specific quantitative measurements use $at$, such as the age someone does something (e.g., $at$ the age of $16$), speed (e.g., $120$ miles an hour), temperature (e.g., boiling $at$ $100$ degrees), or altitude (e.g., $at$ $9,000$ metres).

The preposition $by$ is used for methods of travel (e.g., $by$ car, $by$ train) when the noun is used abstractly without an article. If an article or possessive is present, we revert to $in$ or $on$. We also use $by$ for accidental actions (e.g., $by$ mistake, $by$ chance), though the opposite is $on$ purpose. In passive voice, $by$ identifies the agent of an action (e.g., bitten $by$ a dog) or the creator of a work (e.g., a play $by$ Shakespeare). Additionally, $by$ can mean next to or denote a margin of difference, such as winning a race $by$ $5$ metres or a salary increasing $by$ $10$.$\%$.

Noun, Adjective, and Verb Preposition Combinations

Many English nouns, adjectives, and verbs require specific prepositions. Nouns often take $for$ (demand $for$, reason $for$), $of$ (cause $of$, advantage $of$, picture $of$), $in$ (increase/decrease $in$), $to$ (damage $to$, invitation $to$, solution/answer/key/reply $to$), or $with/between$ (relationship $with$, connection $between$, difference $between$). Adjectives describing character or behavior toward others use $of$ for the person's trait (e.g., nice $of$ you) and $to$ for the recipient of the behavior (e.g., nice $to$ me). Adjective groups also use $about$ (angry/excited/nervous $about$), $with$ (annoyed/satisfied/fed up $with$), $at/by$ (surprised/shocked $at$ or $by$), and $of$ (proud/ashamed/aware/capable/full/short $of$).

Verbs require careful attention to the intended meaning. We talk $to$ or listen $to$ someone, and explain or describe things $to$ someone. We shout $at$ someone when angry, but shout $to$ someone so they can hear us. We throw things $at$ a target to hit it, but throw something $to$ someone for them to catch. Regarding thoughts, we think $about$ something to mean concentrating on it or considering it, but think $of$ to mean producing an original idea or giving an opinion. We hear $about$ news, hear $of$ something to know it exists, and hear $from$ someone to mean we are in contact with them. Other common verb combinations include depend $on$, suffer $from$, believe $in$, congratulate someone $on$, and apply $for$ a job.

Phrasal Verbs: Mechanics and Categories

Phrasal verbs consist of a base verb plus a particle such as $in$, $out$, $on$, $off$, $up$, $down$, $back$, or $away$. These particles can change the verb's meaning entirely, such as break down (stop working) or give up (stop trying). A key grammatical rule involves the position of objects. If the object is a noun, it can often go after the particle or between the verb and the particle (e.g., turn $on$ the light or turn the light $on$). However, if the object is a pronoun like it, them, me, or him, it must go in the middle (e.g., turn it $on$, not turn $on$ it).

Particles suggest general directions of meaning. $In$ and $out$ often refer to entry or exclusion, such as moving $in$ or dropping $out$ of a course. $On$ and $off$ can relate to machines (turn $on/off$), clothes (put $on$, take $off$), or continuation (go $on$, carry $on$). $Up$ and $down$ can refer to physical movement (pick $up$, put $down$) or changes in intensity (turn $up$, speed $up$, slow $down$). $Up$ also frequently implies completion or stopping (use $up$, give $up$, finish $off/up$). $Away$ and $back$ relate to distance and return, such as driving $away$ from a place or being $back$ at a location. Notable phrasal verbs include look after (take care of), look for (search), find out (discover), and put off (delay).

Questions & Discussion

Throughout the study of these units, various functional questions and practice scenarios arise to clarify usage. For example, one must distinguish between the correct forms: I will see you $on$ Friday and I will see you Friday are both acceptable, but I will see you $on$ next Friday is incorrect. Another exercise asks to choose the correct preposition for specific contexts: Mozart was born $in$ Salzburg $in$ $1756$. Another example focuses on phrasal verb word order: when asked if you should throw away a box, if the response uses a pronoun, it must be reported as Don't throw it $away$.

In unit-specific exercises, students are asked to differentiate between at the end and in the end. For instance, in the sentence describing a car problem, we use $in$ the end we sold it to show the final result. In contrast, for the sentence describing a payment, we use $at$ the end of the month to specify the timing. Other practice focuses on the distinction between $at$ and $in$ for positions; for example, there is a notice $on$ the door (surface) but somebody is $at$ the door (location). Finally, phrasal verbs like do up (to repair or fasten) and break up (to separate) are tested in contexts of home renovation or relationships to ensure students grasp both literal and idiomatic meanings.
