Grammar

Words and expressions that are informal and not standard English. Different social groups often use a special vocabulary. Sometimes this is fairly widespread and well understood. In the sentences that follow the slang expressions are in bold type. If Martin is prepared to take the risk, he could be quids in. I just wanted to be sure you weren’t trying to pull a fast one on me. I’m a bit skint at the moment. Some slang is confined to small tightly knit groups who can use it to exclude outsiders. Slang is also often sexual or scatological.
