Sole: Used as an adjective, e.g., the sole survivor.

Why Using "Only" Correctly Matters

Proper use of “only” sharpens your message, reducing misunderstanding. For example:

But if you misplaced it, like “I have five only dollars,” the meaning becomes confusing.

Correct placement ensures your audience understands exactly what you're saying—no ambiguity!
