A concept is an idea or a general notion about something, especially one that helps you understand or organize information. It is more abstract than a specific fact or example.
From Latin 'conceptus', meaning 'something conceived', from 'concipere' ('to take in, to conceive'). It moved into English through French, keeping the link to mental 'conception'.
Think of a concept as a mental folder where you store many examples under one label—like 'chair', covering everything from office chairs to beanbags. Learning deeply often means upgrading your concepts, not just adding more facts.
