Yes, we can express thoughts without the use of modal verbs by using direct statements or different grammatical structures. For example:- With modal verbs: "I can go to the store tomorrow."- Without modal verbs:"I will go to the store tomorrow."Instead of saying something like "You should try this," you could say "It is a good idea to try this." Modal verbs like "can," "could," "should," and "might" often add nuance, but they are not strictly necessary to express ideas.
