What does the prefix multi- mean?

Multi- comes from the Latin multus, which means "much" or "many". It shows plurality: more than one, and usually quite a few.

Multi- or poly-: what is the difference?

Both mean "many", but they have different origins: multi- comes from Latin and poly- from Greek. The difference is not in the meaning, but in the field where they are used. In more formal science poly- is usually preferred, and in business and technology language multi- is preferred. If you want to create a word, notice which one is used in the same setting.

Common mistakes

multitasking = doing several things well at the same time
multitasking = switching rapidly between tasks; research shows the human brain cannot truly execute two cognitive tasks simultaneously

The term "multitasking" comes from computing. Applied to humans, neuroscience shows that what we call "multitasking" is actually "task-switching" — rapid refocusing — which reduces efficiency and quality in both tasks.

multilingual and polyglot are perfect synonyms
both mean "speaking multiple languages," but polyglot often implies advanced proficiency in several languages

"Multilingual" = communicating in more than one language (neutral, broad). "Polyglot" typically implies advanced proficiency in several languages (usually three or more) and carries a stronger connotation of linguistic skill. A country can be "multilingual"; a person who masters six languages might be called "a polyglot."

A trick to remember it

Think of multitasking, doing many things at once: multi- = many. multiply, multitask.
