Free Preposition Finder
A preposition shows the relationship between a noun (or pronoun) and another word in the sentence — usually telling location, time, or direction. 'In,' 'on,' 'at,' 'by,' 'with,' 'for,' 'to,' 'from' are all prepositions. This finder highlights every preposition in your text. To find the nouns and pronouns they connect, try those tools next.

How the Preposition Finder Works
Prepositions are a small, closed class in English — about 100 words total. The finder uses a comprehensive dictionary that catches every standard preposition (about, above, across, after, against, along, among, around, at, before, behind, below, beneath, beside, between, beyond, by, despite, down, during, except, for, from, in, inside, into, near, of, off, on, onto, out, outside, over, past, since, through, throughout, to, toward, towards, under, underneath, until, up, upon, with, within, without).
Rules & Tips
1Prepositions show relationships
Time: 'at noon,' 'on Monday,' 'in 2026.' Place: 'on the table,' 'in the box,' 'under the bed.' Direction: 'to the store,' 'from home,' 'through the door.'
2Prepositions need objects
Every preposition is followed by a noun or pronoun (the 'object of the preposition'). 'On the table' — 'the table' is the object.
3Common prepositional phrases
'According to,' 'because of,' 'in addition to,' 'in front of,' 'on top of' — these multi-word prepositions are also detected.
4Don't fear ending a sentence with a preposition
'That's what I'm worried about' is fine in modern English. The old rule against it has been formally abandoned by most style guides.
