Questions & Answers

Q: What is the main difference between 'when' and 'if'?

The main difference between 'when' and 'if' lies in the certainty of the event. 'When' is used for events that are certain to happen in the future, while 'if' is used for events that may or may not occur, indicating uncertainty. The choice between them depends on the speaker's perception of the event's likelihood.

Q: How can 'if' and 'when' be interchangeable?

'If' and 'when' can be interchangeable when discussing general situations where the meaning of 'if' is similar to 'whenever'. In such contexts, both words can imply the same general condition or repeated action. For instance, 'I keep the air-conditioning on at night if/when the temperature goes above 30 degrees' illustrates this interchangeability.

Q: What does 'in case' signify in conditional sentences?

'In case' is used in conditional sentences to discuss taking precautions or actions because another event might happen. It implies preparation for a possible future situation. For example, 'I’ve brought some candles in case there’s a power cut' indicates readiness for an event that may or may not occur.

Q: Can you give an example of using 'in case' and 'if' differently?

Yes, consider the sentences: 'I’ll fill up the car with petrol in case you need to go to Brighton' and 'I’ll fill up the car with petrol if you need to go to Brighton'. The first implies filling the car as a precautionary measure, while the second suggests waiting for confirmation before taking action.

Q: Why is the present tense used in 'when' clauses for future events?

The present tense is used in 'when' clauses for future events to emphasize certainty and immediacy. Although the event is in the future, using the present tense highlights that the occurrence is definite. For example, 'I’ll give you a ring when I get home' uses the present tense to convey certainty about the future action.
