The word "assemble" in simple terms means to put different parts together to form a complete object or gather a group of people in one place. For example, when you assemble a puzzle, you join all the separate pieces together to create the whole picture. Or, if a teacher asks all students to assemble in the school hall, it means she wants all students to come together in that location.
