Prepositions
Prepositions are one of the most frequently tested topics in the LAT English section because the rules are compact, the traps are predictable, and a student who memorizes the categories below can solve almost any preposition MCQ without needing to "feel" the language.
WHAT IS A PREPOSITION?
A preposition is a word that comes before a noun (or pronoun, gerund, phrase, or clause) and shows that noun's relationship to another word in the sentence.
Example: He goes to college by bus.
- 'to' is a preposition β it comes before the noun 'college'.
- 'by' is a preposition β it comes before the noun 'bus'.
A quick memory trick for the definition itself: PREPOSITION = PRE (before) + POSITION (place) + NOUN, i.e. a word placed BEFORE a NOUN to show its POSITION/relation.
THE PREPOSITION TEST β IS IT REALLY A PREPOSITION?
The same word can function as a preposition or an adverb depending on whether a noun follows it.
- 'He goes in.' β No noun follows 'in', so here 'in' is an ADVERB, not a preposition.
- 'He goes in the room.' β 'in' is followed by the noun 'room', so it is a preposition.
This distinction is a classic LAT trap: examiners test whether students can tell a preposition from an adverb that looks identical.
WHAT CAN FOLLOW A PREPOSITION? (the five things)
A preposition is always followed by one of: a Noun, a Pronoun, a Gerund, a Phrase, or a Clause. It is never followed by a plain verb (base form).
- Noun: interested IN the subject
- Pronoun: angry WITH him
- Gerund (verb+ing acting as noun): good AT swimming
- Phrase: known FOR his honesty
- Clause: worried ABOUT what might happen
THE FIVE CATEGORIES OF PREPOSITION USE
1) LOCATION β in, on, at
- At: a specific point (at the door, at the corner)
- In: an enclosed space (in the box, in the room)
- On: a surface (on the table, on the wall)
Examples: He is standing at the entrance. The keys are in the drawer. The picture is hanging on the wall.
2) DIRECTION (movement) β in, into, on, onto, to, toward
- In: movement to a position inside a space. "She put the groceries in the refrigerator."
- Into: movement from outside to a point inside; emphasizes entering. "The cat jumped into the box."
- On: movement to a position on a surface. "He placed the book on the table."
- Onto: movement from a lower position to a higher one on a surface; emphasizes climbing/jumping. "The cat jumped onto the counter."
- To: movement toward a specific destination or goal. "She is walking to the store."
- Toward(s): movement in a general direction, not necessarily reaching it. "He walked toward the park."
3) TIME β in, on, at, within, by, for, since, during, from-to
- In: longer periods β months, years, centuries. "She was born in July." "We moved here in 2020."
- On: days and dates. "He arrived on Monday." "The meeting is on July 15th."
- At: precise times and fixed expressions. "The train leaves at 5 PM." "She works best at night."
- Within: before a certain point/deadline. "Complete the assignment within a week."
- By: not later than a specific point. "Finish your homework by 8 PM."
- For: duration of an action (a length of time). "She studied for two hours."
- Since: the starting point of an action that continues into the present. "They have lived here since 2010."
- During: a period or event within which something happens. "We met during the conference."
- FromβTo: the starting and ending points of a period. "The office is open from 9 AM to 5 PM."
LAT TRAP: 'for' answers "how long?" (a duration β for two hours), while 'since' answers "starting when?" (a fixed point β since 2010). Mixing these up is the single most common preposition-of-time mistake.
4) PREPOSITIONS WITH VERBS β at, for, with, of, about
Certain verbs are followed by fixed prepositions, and these verb+preposition pairs are frequently tested as fill-in-the-blank items.
- AT (direction/focus): look at, laugh at, stare at
- FOR (purpose/reason): ask for, wait for, search for
- WITH (accompaniment/association): agree with, deal with, collaborate with
- OF (possession/belonging): think of, dream of, approve of
- ABOUT (subject/topic): talk about, worry about, complain about
These combinations should be memorized as fixed pairs (e.g., "agree WITH a person" but "agree TO a proposal") since LAT often tests the exact preposition that idiomatically follows a given verb.
5) SPATIAL RELATION (position of objects relative to each other)
above, below, beside, in front of, behind, between, inside, outside, near, far from, on, under, next to, around, through, across, over, against, adjacent to, amid.
- Above / Below: higher / lower position ("The plane flew above the clouds." / "The valley is below the mountain.")
- Beside / Next to / Adjacent to: at the side of, all near-synonyms ("The lamp is beside the bed." / "The store is next to the bank." / "Her office is adjacent to mine.")
- In front of / Behind: ahead of / at the back of ("He stood in front of the audience." / "She hid behind the tree.")
- Between (two things) vs Among (three or more): "He sat between his parents" (two people) β note LAT sometimes tests 'between' vs 'among' as a pair even though only 'between' appears explicitly here; the rule is between = 2, among = 3+.
- Inside / Outside: within / outside the confines of something ("The keys are inside the drawer." / "They waited outside the building.")
- Near / Far from: close to / distant from ("The park is near our home." / "He lives far from the city center.")
- On / Under: on the surface of / directly beneath ("The book is on the table." / "The cat is sleeping under the bed.")
- Around: surrounding something ("There is a fence around the garden.")
- Through: moving from one side to another within an object ("The tunnel goes through the mountain.")
- Across: on the opposite side, or moving from one side to the other ("The library is across the street.")
- Over: above and covering something ("He held the umbrella over his head.")
- Against: touching or in contact with, often implying pressure/support ("The ladder is leaning against the wall.")
- Amid: in the middle of multiple objects/a crowd ("He stood amid the crowd.")
QUICK-REVISION TABLE FOR EXAM DAY
- Specific point β AT | Enclosed space β IN | Surface β ON
- Entering something β INTO | Climbing/jumping onto a surface β ONTO | Heading to a destination β TO | General direction β TOWARD
- Duration (how long) β FOR | Starting point (since when) β SINCE | Deadline (not later than) β BY | Before a limit β WITHIN
- Two objects β BETWEEN | Three or more β AMONG
WHY IT MATTERS: LAT preposition MCQs are rarely about obscure vocabulary β they are about correctly matching one of the categories above (location, direction, time, verb-preposition, spatial relation) to the sentence's context. Students who drill the FOR-vs-SINCE, IN-vs-INTO-vs-ONTO, and fixed verb+preposition pairs (agree WITH, look AT, wait FOR) cover the large majority of past-paper questions.
