What would the world be without dictionaries? Whenever you don't know a word, the best thing to do is look it up in a dictionary. Dictionaries help you learn words. A word : Gist.
What does it mean? Don't cheat. /When you need a quick summary of the essentials, rather than the whole story or a thorough explanation, you're looking for the gist.\
The word gist has had a variety of meanings in English, but most of them have become unknown. It's either that or the definitions have expired.
A cacophony is a conbonation of unpleasant sounds, often at loud volume. It's what you'd hear if you gave instruments to a group of four-year olds and asked them to play one of Beethoven's symphonies.
A cacophony is a jarring, discordant mix of sounds that have no business being played together. When the orchestra tunes up before a show, it sounds like a cacophony because each musician is playing a completely different tune, at different times, and at different volumes.
