Another Word for Truly
The best single replacement depends on what you mean.
For professional writing, genuinely is often a useful choice when you want to communicate sincerity.

For casual conversation, really is usually the most natural alternative.

When Not to Use Truly

This is acceptable, but a more precise sentence may communicate more.

The second sentence gives the reader specific information instead of relying on emphasis.
