Read the business news, or take part in a business conversation, and you'll come across lots of expressions and idioms that make the subject more vivid and descriptive. Expressions like "flood the market" or "a big cheese" give us strong mental images. But it can be difficult to understand the precise meaning of some other expressions - especially if English isn't your first language. For example, phrasal verbs (such as "drag on", "pick up" or "lay off") don't have clues that help with understanding.
