In vs. With – Which is Correct?
“In” identifies a place, situation, time, condition, or surrounding medium, while “with” identifies companionship, possession, tools, or an accompanying quality. Both are correct, but they are not interchangeable. Choose “in” for inclusion or circumstances and “with” for association, accompaniment, possession, or means in a sentence depending on the intended relationship.
In or With – Which is Correct?
In and with are both correct American English prepositions, but they express different relationships. Use in when someone or something is inside a place, situation, period, condition, or medium. Use with when describing accompaniment, possession, an instrument, a characteristic, or the manner in which something happens.
Compare these sentences:
- She is in the office. The office is the place containing her.
- She is with her manager. Her manager is accompanying her.
- He wrote the note in pencil. Pencil describes the medium.
- He wrote the note with a pencil. A pencil is the tool he used.
The Best Trick to Remember the Difference
Use the inside test for in: if you can imagine a person, object, or idea located inside a place, time, condition, or situation, choose in. Use the accompaniment or tool test for with: if something is alongside someone, belongs to someone, describes someone, or helps produce an action, choose with.
| Word | Part of Speech | Meaning | Example |

How to Use In
Use in to show that someone or something is located inside a physical space. It can also describe inclusion within a group, participation in an activity, a period of time, a condition, or a particular medium or form.
Example 1: The children are playing in the garden.
Example 2: We met in July.
Example 3: She works in finance.
In is also common in expressions involving states or circumstances, such as in trouble, in love, in danger, in progress, and in detail. It can introduce a language, material, or communication format: written in English, painted in oils, or spoken in a quiet voice.
Etymology of the word In
In comes from Old English in, meaning “inside” or “within.” It is related to similar forms in other Germanic languages and has retained its central spatial meaning while developing many abstract uses involving time, condition, participation, and manner.
How to Use With
Use with to show that people or things are together, accompanied, connected, or associated. It can also indicate possession, a tool or instrument, a characteristic, a cause of feeling, or the manner in which an action is performed.
Example 1: Maya went to the conference with her colleague.
Example 2: He cut the paper with scissors.
Example 3: The house with the blue door is for sale.
With is used in both casual and formal English. It frequently follows verbs such as agree, deal, help, provide, and compare: agree with someone, deal with a problem, and provide customers with information.
Etymology of the word With
With comes from Old English wiþ. Its earliest meanings included “against” or “opposite,” but its sense gradually expanded to express association, accompaniment, and connection. The modern meaning developed through these related ideas of being alongside or in relation to something.
