In this episode of 6 Minute Grammar, the hosts delve into the nuances of using the modal verbs "may," "might," and "could." These three words are essential for expressing uncertainty, making predictions, and discussing possibilities in both the present and the future.
At their core, "may," "might," and "could" are used to describe events that are not certain. When followed by an infinitive verb without "to," they function as interchangeable tools to speculate. For instance, regarding dinner plans, one might say, "I may make chicken curry," "I might have steak," or "I could get a takeaway."
Beyond future intentions, these modals are equally effective for making guesses about the present. When an unexpected person enters a studio, the hosts speculate: "She may be from IT," "She might be the new presenter," or "She could be the new studio manager." In these contexts, the speakers are acknowledging a range of potential realities without confirming any as fact.
Forming negatives with these modals is generally straightforward: we use "might not" or "may not." While contractions like "mightn't" or "mayn't" exist, they are noted as being quite unusual in standard speech.
However, a significant linguistic warning is provided regarding the word "couldn't." Learners are cautioned to be careful when discussing future uncertainty. Using "couldn't" often implies an impossible situation in the past rather than a future possibility. For example, in an airport scenario where a plane might be delayed, saying "we couldn't take off" suggests a past impossibility. To express future uncertainty safely, the podcast recommends sticking to "might not" or "may not."
While it is grammatically correct to form questions using "might," "may," or "could" directly (e.g., "Might Catherine have chicken curry?"), the hosts offer a "top tip" to make spoken English sound more natural. They suggest prefacing questions with the phrase "do you think?"
By structuring a sentence as "do you think + subject + might/may/could + infinitive," the speaker achieves a more conversational tone. For example, asking "Do you think Catherine might have chicken curry for dinner?" sounds significantly more fluid than the formal alternative.
