Leaf through means to turn the pages of a book or magazine quickly, looking at it without reading every word. To use leaf through in a sentence, put the reading material straight after the verb: “She leafed through the atlas while the train crossed the bridge.” The verb is inseparable, so the pages cannot be split from through.
Leaf through at a glance
- Leaf through is a transitive phrasal verb: it always takes an object such as a book, album or magazine.
- The verb is inseparable, so the object never comes between leaf and through.
- Its forms are leafs through, leafed through and leafing through.
- It describes light browsing, not careful reading or study.
- The commonest error is splitting the phrase, as in leaf the magazine through.
What does leaf through mean?
Leaf through is a phrasal verb meaning to turn the pages of something quickly and casually, taking in what catches the eye. The Cambridge entry for leaf through keeps the sense to books and printed matter, and the two ideas inside it matter: the motion of the pages, and the absence of close attention. You leaf through a magazine in a waiting room; you do not leaf through a legal contract you must sign.
| Use | Plain meaning | Example sentence |
|---|---|---|
| Browsing pictures | Turning pages to enjoy what you see | He leafed through the photo album with a smile. |
| Scanning for one thing | Flipping pages until something catches your eye | She leafed through the catalogue for winter coats. |
| Passing time | Looking at pages with no fixed purpose | I leafed through an old magazine while I waited. |
One limitation is worth stating plainly. Leaf through is not the same as read through, because it says nothing about understanding or finishing the text. If the reader is meant to study the material, use read through or work through; keep leaf through for the light, unhurried look.
The phrase also carries a faint note of leisure that skim through lacks. Leafing through happens in waiting rooms, on sofas and in bookshops, where nobody expects a result. Once a reader has a deadline, the verb changes to skim, scan or read, because leaf through promises only a pleasant few minutes.
How do you use leaf through in a sentence?
Three grammar facts control every sentence. First, the phrase is transitive, so it needs an object. Second, it is inseparable, so leaf the book through is wrong. Third, the particle never strands at the end: you cannot say the book was leafed through by her with the particle left behind in the same way some phrasal verbs allow. The object simply follows through.
| Pattern | Example | What it signals |
|---|---|---|
| leaf through + object | He leafed through the report. | The object follows the whole phrase. |
| leaf through + object + looking for | She leafed through the album looking for the photo. | Adds a light purpose to the browsing. |
| adverb between verb and particle | He leafed quickly through the stack. | An adverb may sit inside, but the object may not. |
| be leafed through (passive) | The magazine had been leafed through many times. | Passive use is normal and keeps the object as subject. |
| leaf through + pages / book / album | She leafed through the pages of the diary. | The object names the printed thing, not the reading. |
Notice the difference between an adverb and an object. Leaf quickly through the stack is fine, because quickly modifies the verb, but leaf the stack through is impossible, because the stack is the object and must follow through.

Leaf through vs skim through
These two partner verbs are close but not identical. To leaf through is to turn pages lightly and look, while to skim through is to read fast on purpose for the main points. A third cousin, to flip through, stresses the quickness of the turning rather than the reading.
| Attribute | leaf through | skim through |
|---|---|---|
| Core action | Turning pages and looking | Reading quickly for the gist |
| Attention | Light and unfocused | Focused but brief |
| Purpose | Browsing, often no fixed goal | Finding the main points in a hurry |
| Typical object | Magazines, albums, catalogues | Reports, articles, chapters |
| Example | He leafed through the holiday brochure. | She skimmed through the summary before the call. |
Verdict: choose leaf through for casual page-turning and skim through when the reader is after information fast, and remember that neither means the careful work of read through.

The bottom line
Use leaf through in a sentence when someone turns pages lightly, and keep the object after through because the phrase is inseparable.

For a fast search for information, skim through is the closer partner, and for a thorough pass, go through is the verb to reach for.
