The traditional definition of peruse is to read thoroughly or with great care. It does not traditionally mean to skim, to look through, or to browse. All authoritative English reference sources agree on this. But peruse is so often used as a synonym of browse that this secondary definition may someday gain acceptance. The change is not yet fully established, though, and many people still think of this newer use of peruse as wrong.
The word first appeared around the the end of the 15th century. It was formed by adding the prefix per-, which then meant thoroughly, to the verb use, so its original sense was to use thoroughly. The sense to go through carefully or examine developed soon thereafter. Examples of peruse used in the newer sense (to browse or to skim) are easily found in sources from the middle 20th century, but they are rare or nonexistent before then.
Writers in this century often use peruse to mean simply view or observe, suggesting neither thoroughness nor quickness. In these cases, the word is vague because we can’t know whether the author means it in the older sense or the newer one. It often could be taken to mean to look through at one’s own pace, to look through while one is passing through, to look through when one has enough time, or to look through while engaged in something else.
