Frequently asked questions
What is the difference between go off and go off on?
Go off on someone means to direct sudden anger at that person: he went off on the referee. Go off without a preposition can mean explode, sound, spoil, or simply perform superbly, and the meaning is decided by context.
Does 'go off' mean something is good or bad?
In current slang it is usually praise — a song or a performance that goes off is exciting and impressive. But the same phrase describes an angry outburst and, in British English, food that has spoiled, so it is genuinely one of the most context-dependent phrasal verbs in English.
