Edited by Aimie Carlson || By Janet White || Updated on September 27, 2023
"Incase" is often a misspelling of "in case," a phrase meaning if or as a precaution, whereas "encase" means to enclose or cover completely.

Key Differences

“Incase” is generally not a standard word in English and is usually used as a common misspelling of the phrase “in case,” meaning if or as a precaution. It’s a conjunction used to represent the concept of something happening as a contingency or a precautionary measure. On the other hand, “encase” is a standard English word, a verb, used to describe the action of completely enclosing or covering something, often to protect it.
When someone uses “incase” as a misspelling of “in case,” they might be referring to scenarios involving precautions or conditions. For instance, someone might say “Bring an umbrella, in case it rains,” signaling a precautionary measure against possible rain. In contrast, “encase” typically refers to enclosing something within a case, container, or some form of cover, like “The artifact was encased in glass,” emphasizing that the artifact is completely surrounded by glass.
The usage of “incase” to mean “in case” is considered informal and non-standard, and it is recommended to use the two-word form to avoid any confusion or to be grammatically correct. “Encase” is formal and standard, utilized when something is being completely enclosed or covered, usually to offer protection or to isolate it. It has a clear and distinct meaning, making it straightforward in its usage.
In the context of grammar and sentence construction, using “in case” correctly will enhance the clarity and coherence of the statement, specifying it as a condition or a precaution. The word “encase,” when employed correctly, will also lend clarity and precision to the description, accurately conveying the act of enclosing or covering completely.
