What does cramming mean?
Cramming is the practice of studying intensively in a short period, typically in the hours or days immediately preceding an examination. The word derives from the older sense of "cram," meaning to force or pack things tightly into a confined space—a fitting metaphor for squeezing a term's worth of material into a single sleepless night. While cramming remains a near-universal rite of passage among students, educators and memory researchers consistently warn against it: information absorbed this way tends to be quickly forgotten, a phenomenon related to the "spacing effect," which shows that distributed practice produces far more durable learning. Beyond the classroom, cramming can also describe literally overcrowding objects or people into a space that cannot comfortably hold them. Whether applied to facts or furniture, the word always suggests excess pressure, haste, and a certain disregard for limits.
Intensive, last-minute study undertaken in preparation for an examination.
"His cramming paid off just enough for him to scrape a pass."
Usually uncountable; often preceded by adjectives such as "frantic," "last-minute," or "desperate."
The action of forcing or crowding people or things into a space too small to accommodate them comfortably.
"The constant cramming of goods into the warehouse made the aisles impassable."
Despite its popularity the night before an exam, memory research has shown that cramming is one of the least effective ways to learn—the knowledge fades almost as fast as it was forced in.

Etymology of cramming
The noun "cramming" comes from the verb "cram," which has been used since Middle English to mean pressing or stuffing things into a tight space. The verb is of Germanic origin, and is related to Dutch "krammen," meaning to cram or wedge in. Its figurative extension to intensive, last-minute study arose in British university slang, likely in the late eighteenth century, and spread from there into general English use on both sides of the Atlantic.

How cramming is actually used
In the educational sense, cramming carries a mildly negative connotation, implying rushed, superficial learning rather than genuine understanding. It is common in both informal and formal writing about education, though it is especially frequent in student speech and journalism. In British English the informal verb "swot" and phrase "mug up" cover similar ground.
