What does should mean?
Should is a modal verb used to express obligation, duty, advice, and expectation. In “You should apologize,” it recommends or strongly suggests a course of action, often with less force than “must.” It also introduces a reasonable expectation: “The results should be available next week.” In formal English, should can indicate what is necessary or appropriate, and in some constructions it functions as the past form of shall. These distinctions make it one of English’s most useful everyday verbs, since it can move smoothly between recommendation, expectation, and obligation without requiring a separate auxiliary. The word belongs to the same broad semantic family as shall and the phrase “ought to,” but its modern usage is typically less absolute than “must.”

“Should” began as a word about obligation: its Old English ancestor meant that someone was under a duty, long before it became a gentle guide to what we ought to do.
