Prepositions of Direction: To, On (to), In (to)
Graphics for this handout were developed by Jordan Golembeski.
This handout explains prepositions that express movement toward something: to, onto, and into. First, the prepositions will be introduced as a group. Then, the special uses of each one will be discussed.
To, into, and onto correspond respectively to the prepositions of location at, in, and on. Each pair can be defined by the same spatial relations of point, line/surface, or area/volume. To learn more about the spatial relationships expressed by these pairs of prepositions, read the first section of "Prepositions of Location: At, On, and In" before you start reading this handout.
The basic preposition of a direction is "to."
TO: signifies orientation toward a goal
When the goal is physical, such as a destination, "to" implies movement in the direction of the goal.
When the goal is not a physical place, for instance, an action, "to" marks a verb; it is attached as an infinitive and expresses purpose. The preposition may occur alone or in the phrase in order. The two uses can also occur together in a single sentence:
The other two prepositions of direction are compounds formed by adding "to" to the corresponding prepositions of location.
The preposition of location determines the meaning of the preposition of direction.
ON + TO = onto: signifies movement toward a surface
IN + TO = into: signifies movement toward the interior of a volume
("To" is part of the directional preposition toward, and the two mean about the same thing.)
With many verbs of motion, "on" and "in" have a directional meaning and can be used along with "onto" and "into."
This is why "to" is inside parentheses in the title of the handout, showing that it is somewhat optional with the compound prepositions. Thus, the following sentences are roughly synonymous:
To the extent that these pairs do differ, the compound preposition conveys the completion of an action, while the simple preposition points to the position of the subject as a result of that action. This distinction helps us understand how directional and locational prepositions are related: they stand in the relationship of cause and effect.
The paper went into the garbage can.
Position of subject: the paper is in the garbage can.
The crab washed up onto the shore.
Position of subject: the crab is on the shore.
See the sections below for some exceptions to this rule.
Uses of "To"
"To" occurs with several classes of verbs.
Verb + to + infinitive
Verbs in this group express willingness, desire, intention, or obligation.
Willingness: be willing, consent, refuse
Desire: desire, want, wish, like, ask, request, prefer
Intention: intend, plan, prepare
Obligation: be obligated, have, need
I refuse to allow you to intimidate me with your threats.
I'd like to ask her how long she's been skiing.
I plan to graduate this summer.
Henry had to pay his tuition at the Bursar's office.
In other cases, "to" is used as an ordinary preposition.
Verbs of communication: listen, speak (but not tell), relate, appeal (in the sense of 'plead,' not 'be attractive')
Verbs of movement: move, go, transfer, walk/run/swim/ride/drive/ fly, travel
Except for transfer, all the verbs in listed here can take toward as well as to. However, "to" suggests movement toward a specific destination, while "toward" suggests movement in a general direction, without necessarily arriving at a destination:
(It was headed in the direction of a storm cloud; it may not have reached or flown through the cloud.)
(Drive in the direction of the city limits; turnoff may be before arriving there.)
(I actually want to arrive at the airport.)
Uses of "Onto"
"Onto" can generally be replaced by "on" with verbs of motion.
Dietrich jumped on(to) the mat.
Huan fell on(to) the floor.
Athena climbed on(to) the back of the truck.
Some verbs of motion express the idea that the subject causes itself or some physical object to be situated in a certain place (compare the three example directly above).
Of these verbs, some take only "on." Others take both "on" and "onto," with the latter being preferred by some speakers.
The plane landed on the runway. (not "onto" the runway)
Sam hung the decoration on the Christmas tree. (not "onto" the tree)
He placed the package on the table. (not "onto" the table)
Joanna spilled her Coke on the rug. (not "onto" the rug)
Samir moved the chair on(to) the deck.
The crane lowered the roof on(to) the house.
The baby threw the pot on(to) the floor.
Verbs taking only "on" are rare: "set" may be another one, and so perhaps is "put." Other verbs taking both prepositions are "raise," "scatter" (when it takes a direct object), "pour," and "add."
The farmer scattered seed on(to) the fertile ground.
We're adding on a wing at the back of the building.
We're adding a porch onto the house.
In "We're adding on a wing at the back of the building," "on" is really part of the verb, while in "We're adding a porch onto the house," "onto" is a simple preposition. This contrast points to a fairly important and general rule:
Simple prepositions can combine with verbs, but compound prepositions cannot.
Note also that in "The farmer scattered seed on(to) the fertile ground", the word "on" has its ordinary meaning of a position on a surface, but in this case the surface is vertical rather than horizontal— the side of a building.
There are a number of verb-preposition combinations that are similar to "add on" but have the meaning "of continuing or resuming an action" when used in the imperative mood.
Except for "hang," which takes both "on" and "onto," the following verbs all occur only with "on." The meanings of these combinations, some of which are idiomatic, are given in parentheses. Not all of them have the force of a command.
- Hang on / Hang onto the rope ("continue to grasp tightly")
- Carry on ("resume what you were doing")
- Cail on ("resume or continue sailing")
- Dream on ("continue dreaming"; a humorous way of saying "that is an unattainable goal")
- Lead on ("resume or continue leading us")
- Rock on ("continue playing rock music")
Uses of "Into"
With verbs of motion, "into" and "in" are interchangeable except when the preposition is the last word or occurs directly before an adverbial of time, manner, or frequency.
In this case, only "in" (or "inside") can be used.
The patient went into the doctor's office. The patient went in. (not "into")
Our new neighbors moved into the house next door yesterday. ("to take up residence in a new home'")
Our new neighbors moved in yesterday.
In "Our new neighbors move in yesterday," the last word is the time adverbial yesterday, so the object of the preposition in can be omitted. Of course, in an information question, "into" also can be last word except for an adverbial when its object is questioned by a wh- word:
Now what kind of trouble has she gotten herself into?
Now what sort of trouble is she in?
Verbs expressing stationary position take only "on" or "in" with the ordinary meanings of those prepositions.
If a verb allows the object of the preposition to be omitted, the construction may have an idiomatic meaning.
The cat sat on the mat.
The doctor is in his office.
The doctor is in. ('available for consultation')
"In(to)" has two special uses with "move."
When "move in" is followed by a purpose clause, it has the sense of "approach."
The lion moved in for the kill.
The police moved in to rescue the hostages inside the building.
In "The lion moved in for the kill" and "The Police moved in to rescue the hostages inside the building," "in" is part of the verb, so "into" cannot be used. We cannot say: "The lion moved into for the kill."
When "into" is used with move, it functions as an ordinary preposition to convey the idea of moving something from one place to another.
Prepositions of Location: At, In, On
Graphics for this handout were developed by Michelle Hansard.
Prepositions expressing spatial relations are of two kinds: prepositions of location and prepositions of direction. Both kinds may be either positive or negative. Prepositions of location appear with verbs describing states or conditions, especially be; prepositions of direction appear with verbs of motion. This handout deals with positive prepositions of location that sometimes cause difficulty: at, on, and in.
The handout is divided into two sections. The first explains the spatial relationships expressed by the three prepositions. The second examines more closely the uses of in and on.
Dimensions and Prepositions
Prepositions differ according to the number of dimensions they refer to. We can group them into three classes using concepts from geometry: point, surface, and area or volume.
Prepositions in this group indicate that the noun that follows them is treated as a point in relation to which another object is positioned.
Prepositions in this group indicate that the position of an object is defined with respect to a surface on which it rests.
Prepositions in this group indicate that an object lies within the boundaries of an area or within the confines of a volume.
Notice that although in geometry surface and area go together because both are two-dimensional, in grammar area and volume go together because the same prepositions are used for both.
In light of these descriptions, at, on, and in can be classified as follows:
at .... point
on .... surface
in ... area/volume
The meanings of the three prepositions can be illustrated with some sample sentences:
All of these sentences answer a question of the form, "Where is _______?" but each gives different information. Before going on, explain to yourself the spatial relations shown in each sentence.
1) locates a car in relation to a house, understood as a fixed point.
2) treats the house as a surface upon which another object, the roof, is placed.
3) locates the house within a geographical area.
4) treats the house as a three-dimensional structure that can be divided into smaller volumes, namely, rooms, inside one of which is an object, the fireplace.
At calls for further comment. Because it is the least specific of the prepositions in its spatial orientation, it has a great variety of uses. Here are some of them:
In 5a), the bank can be understood as a point defining Tom's location, much as in 1) above. It makes less sense to think of a fair as a point in 5b) since fairs are usually spread out over a fairly large area. Probably at is used in this case just because it is the least specific preposition; it defines Sue's location with respect to the fair rather than some other place.
In 6a), at exhibits its cause/effect relationship with to, which cannot be used here: arrival at a place is the result of going to it. For more on this relationship, see the handout Prepositions of Direction: To, (On)to, (In)to.
7a) and 7b) show that with certain verbs of motion at may be used with the same meaning as its directional counterpart to, that is, direction toward something.
Choosing Between "In" and "On"
Nouns denoting enclosed spaces, such as a field or a window, take both on and in. The prepositions have their normal meanings with these nouns: on is used when the space is considered as a surface, in when the space is presented as an area:
Notice that in implies that the field is enclosed, whereas on implies only that the following noun denotes a surface and not necessarily an enclosed area:
When the area has metaphorical instead of actual boundaries, such as when field means "academic discipline," in is used:
Several common uses of in and on occur with street. The first two follow the general pattern of in and on usage. The third is an idiom that must be learned as a unit.
(This is an idiom meaning that he's poor.)
In a), the street is understood as an area enclosed by the sidewalks on either side. Compare b) with the discussion of sentence 3) in the first section. Here, on locates the house on either side of Third Street; it doesn't mean that the street is a surface on which the house sits. Because the street is understood as a line next to which the house is situated, on functions much like at in its normal use; in other words, it locates the house in relation to the street but does not specify the exact address. For that purpose, at is used because the address is like a particular point on the line. Compare: "Our house is at 323 Third Street." In c), out on the street is an idiom meaning "poor" or "destitute."
In and on are also used with means of transportation: in is used with a car, on with public or commercial means of transportation:
on the bus
on the plane
on the train
on the ship
Some speakers of English make a further distinction for public modes of transportation, using in when the carrier is stationary and on when it is in motion.
The passengers sat in/on the plane awaiting takeoff.
