Question

Select the appropriate modal for the expression given : 
When _____ we expect you ? (possibility)

Accepted Answer

1. Explanation for Option 1 ("may"):

The modal "may" is used to express possibility or permission. In the context of the question, "When may we expect you?" implies that there is a possibility of expecting someone at a certain time. The use of "may" suggests that the timing is not definite and is subject to change, which aligns with the concept of possibility. Therefore, "may" is the appropriate choice for expressing the uncertainty or potentiality of the event.

2. Explanation for why the other options are incorrect:

- Option 2 ("will"): The modal "will" is used to express certainty or a future action that is definite. Using "will" in the sentence "When will we expect you?" implies that the expectation is certain and predetermined, which does not align with the notion of possibility. Therefore, "will" is not suitable for expressing possibility in this context.

- Option 3 ("have to"): The phrase "have to" indicates obligation or necessity. If we say "When have to we expect you?" it would imply that there is a requirement or obligation to expect someone at a specific time, which does not convey possibility. Thus, "have to" is not appropriate for expressing possibility.

- Option 4 ("dare"): The modal "dare" is typically used to express challenge or defiance, often in the context of taking a risk. It does not convey possibility in the context of expecting someone. Therefore, "dare" is not suitable for the expression of possibility in this sentence.

In conclusion, "may" is the correct modal to use in the sentence to express the possibility of expecting someone, as it appropriately conveys the uncertainty and potentiality of the event.
