What does cram mean?
To cram is to force something into a space too small to hold it comfortably — packing clothes into an overstuffed suitcase, squeezing people into a crowded room, or stuffing papers into a bulging folder. By extension, the word has become the standard informal term for intensive, last-minute study: students who cram are trying to compress a large amount of material into a short time, usually the night before an examination. The metaphor linking the two senses is apt — both involve forcing more than fits into a limited container, whether a drawer or a memory. Cram carries connotations of haste and strain rather than thoroughness; teachers often contrast cramming with sustained revision. The word functions as both verb and noun, and its past participle "crammed" is common in descriptions like "a crammed schedule" or "a room crammed with furniture," making it a versatile word for describing any situation of uncomfortable fullness or hurried effort.
To force or pack something into a space with difficulty; to fill completely; also, to study intensively over a short period, especially before an examination.
"They crammed six people into a four-seat car."
When used transitively for study, British English often uses "cram up on/for," while American English favors "cram for."
An act of intensive last-minute study, or (rare) a state of being packed tightly.
"An all-night cram got him through the test, but he forgot everything a week later."
The word for last-minute exam studying comes from the same idea as shoving too many clothes into an overstuffed suitcase — your brain gets treated like that suitcase.

Etymology of cram
"Cram" originated in late Middle English, first recorded around the fifteenth century, meaning to feed animals excessively or forcibly — a sense still preserved in the term "crammer" for a device used to force-feed poultry. It likely developed from Old English and Middle Dutch/Germanic roots related to pressing or squeezing, reflected in related words such as "cramp." The studying sense arose in student slang, becoming widespread by the nineteenth century, especially in British universities before spreading to American campuses.
