Daniela teaches Italian in a classroom, complete with blackboard, chalk, eraser, and students. Her lessons are very popular and people love her spontaneity and teaching style. She addresses grammatical topics one by one, geared to both beginning and intermediate level students.
With the relative superlative, we compare one element with an entire group, as for example, "She is the most beautiful of all." In English we distinguish between "more" and "most," but in Italian, the presence of the article before the noun or before the comparative word is what makes the difference.
