it is sad that she could not arrive. could you pl explain the position and parts of speech of 'IT' in the given sentence
The word "It" is serving as the subject of this sentence, but it's a pronoun that has no antecedent in this construction. It's simply used as filler!

Good sentences will not begin with "it."
