What are modals of speculation? Modals of speculation are modal auxiliary verbs which express degrees of certainty. In other words, they describe a fact or situation that is definite, probable, possible, or impossible from the speaker's point of view. (As the speaker is speculating, he/she may be wrong.) Here we'll focus on speculating about present or future events. For example: I wish buy a new computer this summer, if I can afford it. He might go back to school for his Master's Degree next year, but he hasn't decided yet.
