Before you swap out "of course" for something fancier, run through this quick list. It'll save you from sounding like a tool.

Check the formality level: Is this a boardroom or a bar? Pick a word that fits the room, not one that makes you stand out for the wrong reasons.

Avoid overuse: Drop "indubitably" too many times and people will start rolling their eyes. Use it like a spice, not the whole meal.
Test the flow: Say it out loud. If it feels like you're forcing it, dial it back. "Certainly" is always a solid fallback.
Match the audience: "Perforce" might kill it in a poetry reading but totally confuse your team at a meeting. Know your crowd.
