Conditional sentences are very useful at work. The zero conditional describes facts and rules: 'If you press this button, the machine stops.' The first conditional talks about real future possibilities: 'If we finish the project on time, the client will be happy.' You can also use 'unless' instead of 'if not': 'Unless we act now, we will lose the contract.' Other useful phrases are 'as long as' and 'provided that': 'I will approve the budget, provided that the costs are clear.' Conditional language helps you plan, negotiate, and make decisions in English.

💡 Did you know? Conditional sentences exist in almost every language, but English is unusual in having four distinct types (zero, first, second, third). Many languages only have two.
