When it comes to introducing a topic or concept, there are various synonyms that can be used to add variety to your writing or speech. Instead of using the word "introduces" repeatedly, you can consider using words like "presents", "intimates", "previews", "reveals", "unveils", "announces" or "initiates". Each of these synonyms adds a slightly different nuance to the introduction, helping to keep your audience engaged and interested in the content. So, whether you're writing an essay, giving a presentation or having a conversation, be sure to keep these synonyms in mind to elevate your communication skills.
