Books that help with debate and clear articulation

I’m looking for book recommendations that help with debate, articulation, and expressing ideas clearly.

I want to get better at putting my thoughts into words, speaking with confidence, and holding my ground in discussions. This could be formal debates or just everyday conversations.

Fiction or non-fiction is fine. Philosophy, essays, classics, psychology, or even novels with strong dialogue all work.

I’m less interested in hype and more in books that actually sharpen thinking and language.

If a book helped you argue better, think clearer, or speak with more control, I’d like to hear about it.

Thanks.
