Why is there an elephant in the room? How can a story have holes like Swiss cheese? English idioms use vivid images whose meanings are not always clear from the individual words.
This guide explains 40 colorful expressions, with natural examples and notes about tone. Some are everyday idioms; others are informal words, phrasal verbs or pop-culture sayings. Recognizing them helps you understand English, but you do not need to force them into every conversation.
Learn each expression as a whole phrase. Its image can help you remember it, but an entertaining origin story is not necessarily a verified history.

Practice with context
Choose three expressions and write a situation for each. Check the grammar as well as the meaning: “gets my goat,” “bit the dust,” and “went belly up” use different forms. Avoid critical labels such as “wet blanket” or “wet behind the ears” unless you understand how the listener will take them.
Dictionary checks: get someone’s goat, hot potato, and fat chance.
