<span>Lady Macbeth says that to Macbeth in act 3, scene 4</span>
I don't understand the question you are asking, is it supposed to be in regards to something else?
The answer would be preposition. "After some delay" is a prepositional phrase, and "After" is the preposition.
- There isn't an interjection anywhere, which is an abrupt remark.
- There isn't an adverb, which is a modifier that modifies adjectives, verbs, or other adverbs and answers the questions "How? When? Where?"
- And there is no conjunction, which is a word that connects clauses.
